ABSTRACT 

 

As part of the Nuclear Regulatory Commission safety analysis computer code development 

efforts, the Rod Bundle Heat Transfer Test (RBHT) facility has been designed and constructed at 

The Pennsylvania State University. The test series described in this report is the steam cooling 

tests. A total of 35 steady-state steam cooling experiments was performed in the RBHT. The 

purpose of the experiments was to examine the steady-state convective heat transfer from the 

heater rods to single-phase superheated steam in prototypical rod bundle geometry for computer 

code model development and validation. 

The Rod Bundle Heat Transfer Facility has a full length, 3.66 m (12 ft), 7 by 7 rod array with 

typical Pressurized Water Reactor rod diameters of 9.49 mm (0.374 in) and a rod pitch of 12.59 

mm (0.496 in). The heater rods had a top skewed power shape with a peak to average power of 

1.5 at the 2.74 m (9 ft) elevation. The RBHT facility has been designed using prototypical mixing 

vane spacer grids. 

The bundle inlet steam temperature was held at saturation for the given test pressure and the 

inlet Reynolds number ranged from 1,400 to 30,000 with most of the experiments at the lower 

Reynolds number range. The facility was instrumented to measure the quantities necessary for 

determining local convective heat transfer coefficients that reflect the heat transfer enhancement 

caused by mixing vane grids. The measured quantities include vapor temperatures at 

sub-channel centerlines, mixing vane grid temperatures, a detailed axial pressure drop along the 

bundle length, absolute pressure in the upper plenum, rod temperatures upstream and 

downstream of mixing vane grids, and vapor flow rates in and out of the bundle.

FOREWORD 

A loss-of-coolant accident (LOCA) is one of the primary postulated accidents that must be 

considered in the design of nuclear power plants. The plant response to such an accident, 

including the performance of safety systems that are designed to mitigate the accident, is mainly 

analyzed using computer codes. For effective analyses of accidents and operational transients, 

the U.S. Nuclear Regulatory Commission (NRC) consolidated earlier thermal-hydraulics analysis 

codes into one called TRACE. 

The NRC is now assessing and improving the TRACE code as weaknesses are identified. 

One such weakness is inaccurate prediction of peak clad temperatures of fuel rods, particularly 

in the later stage of a large-break (LB)LOCA, called the reflood phase. Specifically, the reflood 

models currently employed in the TRACE code are not sufficiently accurate and, consequently, 

improved models must be developed to provide necessary support for risk-informed regulations. 

Accurate prediction of the consequences of an LBLOCA is important because this is one of 

the limiting postulated accidents used to determine whether plant design parameters (such as 

power densities, equipment sizes, etc.) have been appropriately selected to ensure safety. 

As the NRC places increasing emphasis on risk-formed regulations, the agency needs a more 

accurate and reliable computer code to obtain realistic (rather than conservative) predictions. 

To develop better computer code models for an LBLOCA, we need detailed, fundamental data 

that show heat, mass, and momentum exchanges. Some of these detailed data have only recently 

become possible because of recent advances in instrumentation technology for two-phase flow 

measurements. Consequently, to acquire detailed, fundamental data for use in developing 

models for an LBLOCA, the NRC sponsored the construction of a rod bundle heat transfer 

(RBHT) test facility and completion of four test series; reflood tests, liquid-gas interfacial drag 

tests, steam cooling tests without liquid droplet injection, and steam cooling tests with liquid 

droplet injection. 

This report presents the results of steam cooling tests without liquid droplet injections. The data 

from these tests will be used to develop and assess a steam cooling model which is a 

component of a LOCA model for the TRACE code. The results of other test series will be 

reported in separate reports. 

With improved data and code models for an LBLOCA, we can more accurately predict 

the consequences of LBLOCA accidents and provide better technical bases for regulations 

associated with such accidents. As a result, this study will help to achieve the NRC’s strategic 

performance goals of making the agency’s regulations more effective, efficient, and realistic.

EXECUTIVE SUMMARY 

A series of steady-state, low to intermediate Reynolds number steam cooling experiments have 

been performed in the Nuclear Regulatory Commission/Penn State University Rod Bundle Heat 

Transfer (RBHT) Test Facility. As part of the Nuclear Regulatory Commission safety analysis 

computer code development efforts, the Rod Bundle Heat Transfer test facility has been 

designed and constructed at The Pennsylvania State University. The Rod Bundle Heat 

Transfer (RBHT) Facility is a full length simulation of a portion of a Pressurized Water Reactor 

(PWR) fuel assembly. The bundle is a 7 by 7 rod array with four unheated corner rods and 45 

heated electrical rod which simulate a 17 by 17 PWR fuel assembly. The rod Bundle Heat 

Transfer Facility is full length, 3.66 m (12 ft), with typical PWR rod diameters of 9.49 mm (0.374 

in) and a rod pitch of 12.59 mm (0.496 in). The heater rods had a top skewed power shape with a 

peak to average power of 1.5 at the 2.74 m (9 ft) elevation. The experiments were performed 

using saturated to slightly superheated steam at the bundle inlet which then became 

superheated along the bundle length. The ranges of conditions for the experiments were 

pressures from 137.9 to 413.7 kpa (20 to 60 psia), steam inlet Reynolds numbers from 1400 to 

30,000. Peak heater rod temperatures varied approximately from 400 to 650 degrees C (750 to 

1200 degrees F), and bundle powers from 10 kw to 140 kw. Typical PWR mixing vane spacer 

grids were simulated in the RBHT bundle. 

There were approximately 500 channels of transient data recorded for each test including the 

bundle power, heater rod temperatures, upper plenum pressure, inlet steam flow rate, 

superheated vapor temperatures in the bundle, spacer grid temperatures, and the detailed axial 

bundle pressure drop. There were a total of 12 experiments that were performed and reported to 

the Nuclear Regulatory Commission. There are 35 data sets from these experiments were 

qualified and submitted to the Nuclear Regulatory Commission data bank for analysis and code 

validation purposes. 

The steam cooling data was reduced to calculate the convective heat transfer coefficient for the 

instrumented heater rods. To obtain an expression for the sub-channel bulk fluid temperature, 

the steam probe sub-channel measurements at the center of the sub-channel were analyzed 

using an expression that was derived based on the heat/momentum transfer analogy approach. 

Using this methodology, the vapor temperature point measurements were used to calculate the 

bulk sub-channel vapor temperature. 

The local heat transfer coefficients and Nusselt number values were calculated axially along the 

rod bundle. The increased heat transfer effects downstream of the mixing vane spacer grids 

used in the RBHT was clearly observed from the data. The fully-developed heat transfer data 

was compared to several single phase heat transfer correlations and best correlation that 

represented the RBHT data was recommended. 

The measured axial pressure drop data was also analyzed to calculate the mixing vane grid loss 

coefficient as a function of Reynolds number.

1. INTRODUCTION 

The Pennsylvania State University and United States Nuclear Regulatory Commission (NRC) 

have designed and built a Rod Bundle Heat Transfer (RBHT) facility to investigate the thermal 

hydraulic behavior of a nuclear fuel assembly. [1] The goal was to obtain heat transfer and 

pressure drop data during steady state superheated steam flow, using an electrically heated rod 

bundle. The experiments will provide insight into the physical phenomena occurring in a 

nuclear fuel assembly during a postulated loss-of-coolant-accident (LOCA). 

Best estimate thermal hydraulic safety codes are currently used to evaluate accident scenarios 

and predict the behavior of the reactor core. [2,3] The codes in use have uncertainties and 

conservatism and may not accurately represent the thermal hydraulic phenomena during a 

postulated LOCA. Improved experimental data from the RBHT facility will help reduce these 

uncertainties and improve the accuracy of the computer codes and models. Therefore, the 

experiments performed in the RBHT facility were specifically designed for model development 

and computer code validation. 

Steady state steam cooling experiments have been performed in the RBHT facility to obtain 

single-phase heat transfer coefficients within the rod bundle that reflect the heat transfer 

enhancement caused by mixing vane grids. Mixing vane grids improve heat transfer by 

providing subchannel blockage, which creates additional turbulence, flow separation, and mixing. 

The RBHT steam cooling experiments were performed at various powers, pressures, and a wide 

range inlet Reynolds numbers. The measured quantities include vapor temperatures at 

subchannel centerlines, mixing vane grid temperatures, a detailed axial pressure drop along the 

bundle length, absolute pressure in the upper plenum, rod temperatures upstream and 

downstream of mixing vane grids, and vapor flow rates in and out of the bundle. Inlet and outlet 

conditions as well as fluid and rod temperatures were monitored during the experiments to 

ensure accurate quasi-steady state data was collected. 

The data was reduced and heat transfer coefficients were calculated on a subchannel basis at 

heater rod thermocouple locations within the inner 5x5 bundle. The heat transfer coefficient is a 

function of the subchannel mean bulk fluid temperature, heater rod outside wall temperature, and 

surface heat flux. The mean bulk temperature could not be measured directly. Thus, in order 

to calculate the local heat transfer coefficient, a method based upon the analogy of momentum 

and heat transfer was developed to correlate the local mean bulk temperature with respect to the 

local subchannel centerline temperature, which could be measured. 

Mixing vane grid loss coefficients were calculated using the detailed axial pressure drop data. 

Pressure drop measurements were taken across bare bundle spans and spans which contained 

one or more mixing vane grids. Pressure drop data was only used from the beginning of 

experiments because it was seen that water was evaporating out of the pressure cell reference 

legs as the test progressed. This does not invalidate any steady-state windows achieved at 

least in terms of heat transfer, it does however limit the pressure drop data available for 

calculating mixing vane loss coefficients. 

This report provides a summary of the data obtained, the data reduction methods and 

assumptions used in reducing the data as well as the uncertainty in the experimental data and 

the derived quantities from the data. A full set of the experimental data has been transmitted to 

the NRC data bank.

2. TEST FACILITY DESCRIPTION 

The RBHT facility was developed by PSU and the NRC. The facility was designed to conduct 

systematic separate effects tests under well-controlled laboratory conditions in order to generate 

fundamental rod bundle heat transfer data including: single-phase steam cooling tests, 

two-phase level swell, steam flow tests with and without droplet injection, inverted annular film 

boiling tests, and dispersed flow film boiling reflood heat transfer tests. The facility is capable of 

operating in steady-state forced and variable reflood modes covering a wide range of flows and 

heat transfer conditions at pressures from 1.0 to 4.02 bars (20 to 60 psia). 

Figure 2-1: RBHT Test Facility Schematic. 

The test facility, as shown in Figure 2-1 and Figure 2-2, is a once-through flow facility in which 

either water or steam can enter the lower plenum and flow upward through the rod bundle. The 

lower plenum is attached to the bottom of the flow housing and is used as a reservoir for the 

coolant prior to injection into the rod bundle during reflood. The upper plenum serves as the 

first stage for phase separation and liquid collection of the two-phase effluent exiting the rod 

bundle. The liquid phase separates from the flow due to the sudden expansion from the bundle 

to the larger plenum flow area.

The facility has a large and small liquid carryover tank provided to collect the liquid carryover in 

the fluid flow in order to measure the amount of entrainment in the flow. The de-entrained liquid 

from the upper plenum drains into the top of a 25.6 mm tube, which extends inside a small 

carryover tank to detect and measure the carryover liquid. This tank collects and measures the 

amount of liquid overflow from the smaller carryover tank. A centrifugal two-phase separator is 

located downstream of the upper plenum also acts to separate out the remaining liquid flow from 

the vapor flow such that the vortex meter at the exit of the steam pipe will measure single phase 

vapor flow. There is a third liquid collection tank on the phase separator, which measures the 

separated liquid. 

A pressure-damping tank located before the vortex flow meter and pressure control valve acts to 

damp out any pressure oscillations to maintain tight pressure control on the facility. Separating 

the exit flows from the bundle provides a means of calculating a transient mass balance as well 

as an energy balance on the facility. 

The RBHT facility consists of a 7x7 bundle with 45 heated full-length electrical heater rods, which 

simulates a portion of a 17x17 similar fuel rod assembly, as shown in Figure 2-3. The letters in 

the figure indicate whether a heater rod is instrumented (I), not instrumented (U), or a support rod 

(S). The electrically powered heater rods have a diameter of 9.49 mm (0.374 in) and a square 

pitch of 12.59 mm (0.496 in). There are four unheated Inconel support tubes, one in each 

corner, which provide structural support for the bundle. Mixing vane grid instrumentation is 

routed out of the rod bundle via the support rods. The heater rods have a 3.66 m (144 in) 

heated length with a skewed axial power profile with the peak power located at the 2.74 m (108 

in) elevation, as seen in Figure 2-4. 

The spacer grids, which are used in the bundle have mixing vanes, as seen in Figure 2-5, which 

improves heat transfer downstream of the grids. These grids have high blockage, the projected 

area of the mixing vanes on the top plane of the grid is 39 percent of the total flow area such that 

the flow is accelerated through the grids and entrained droplets can be shattered. 

In the RBHT facility, subchannel instrumentation is used to measure the local vapor temperature 

at subchannel centers. Measurements of the subchannel vapor temperature were made using 

two types of miniature thermocouple probes. The first type of miniature thermocouple used is 

suspended from the mixing vane grids and faces into the flow. The thermocouples have a 0.38 

mm diameter and are supported by 2.44 mm long Inconel tubes which are tack welded to the 

mixing vane grids. The thermocouple leads are routed along the grid straps to the corner 

support tubes and out of the bundle. 

The same type of thermocouples are spot welded to the mixing vane grid walls which measure 

the grid temperature to determine if the grid is dry or quenched. These thermocouple leads are 

also routed to the corner support tubes and out of the bundle.

The second subchannel vapor measurement is made using traversing thermocouple rakes which 

consist of three 0.38 mm diameter thermocouples attached to a thin piece of Inconel shim that is 

welded to a small tube that can be moved to different radial positions within the bundle, as shown 

in Figure 2-6. The thermocouples are located one rod pitch (12.6 mm) apart on the Inconel 

shim and can measure vapor temperatures at three different subchannel centers within the 

bundle. There are 13 traversing thermocouple rakes at different axial positions, most of which 

are powered by a stepping motor that allows the rake to traverse across a subchannel centerline.

A boiler with a capacity of 2613 kg per hour at 10.3 bars provides steam for the experiments. 

The boiler is connected to the lower plenum by means of stainless steel piping equipped with a 

Vortex flow meter to measure steam flows. The piping also has fluid and wall thermocouples, a 

V-ball control valve, and a quick acting solenoid valve. Electrical heaters on the outside of the 

flow housing perform preheating of the facility test components prior to each experiment. 

The test facility instrumentation is designed to measure temperatures, power, flows, liquid levels, 

pressures, void fractions, droplet sizes, droplet distribution, and droplet velocities. There are 

approximately 500 channels of instrumentation for the facility. Overall and transient mass and 

energy balances, mass inventories, carryover liquid, and steam flows can be calculated. 

Steady state steam cooling experiments were performed with steam at superheated conditions. 

Steam entered the rod bundle through the lower plenum, passed through the heater rods, and 

exited via the upper plenum to the exhaust piping. The boiler steam injection rate was 

computer controlled and was verified for the correct pressure and temperature. The steam 

injection line was preheated to avoid any condensation. After approximately fifteen minutes of 

preheating the injection line, the inlet valve to the bundle was opened slightly to preheat the 

bundle and exit lines. The bypass lines around the rod bundle were closed during this 

procedure. The lower plenum, carryover tanks, and steam separator tanks were also drained at 

this time. In order to account for any carryover from the boiler, the tanks had to be drained to 

accurately measure the liquid. Once the bundle was preheated to saturated vapor conditions, 

the bundle power was set at the desired power level. As the fluid flow stabilized for each matrix 

test condition, steady-state flow conditions were approached. Data was recorded for the entire 

length of the test duration, which included warm-up through shutdown. 

Table 2-1 below shows the RBHT steam cooling test matrix which indicates the actual boundary 

conditions of these 21 unique tests. The test matrix was made prior to conducting the steam 

cooling experiments and was used as a guide to ensure the experiments would cover the full 

range of conditions shown in the test matrix. Note that the real conditions achieved during the 

experiments are close to the as designed conditions however, they do not match exactly and the 

real test conditions should and are used in this report for any data manipulation. The real 

conditions achieved for each valid steady-state window can be found on the summary and 

comment sheets in Appendix A.

3. CALCULATION METHODS 

3.1 Heater Rod Outside Wall Temperature and Heat Flux 

The DATARH program was used to calculate the transient heater rod outside surface 

temperatures, and the total surface heat flux. The surface heat flux and the outside wall 

temperature represent a total heat transfer from the heater rod surface and would include 

radiation heat transfer as well as convection. The transient results from DATARH were time 

averaged to get steady state values which were used in subsequent calculations. Note that the 

steam cooling tests were performed under quasi-steady conditions. As such, DATARH was 

used mainly to account for the resistance across the cladding in determining the surface 

temperatures and to assure that steady-state conditions existed. 

Program DATARH.F contains the source code to perform an inverse heat conduction calculation 

in an electrically heated rod, in which internal cladding thermocouples exist. 

The purpose of the code is to calculate the surface temperature and the surface heat flux for the 

heater rods. The program uses experimental data, heater rod dimensions, and material 

properties to perform calculations. The mathematical model for the calculations is described in 

Section 3.1.1 below. 

The program input described herein has been modified for the RBHT experiments from the 

DATARH.F program used for the FLECHT-SEASET experiments. [4] Differences between 

heater rods used in the FLECHT-SEASET experiments and the RBHT experiments (e.g., rod 

dimensions, differences in rod internal materials) have been accounted for in this version of the 

program. 

The sections that follow describe the structure of the source program, RBHT rod geometry and 

materials, and the input files required for executing the current version of the program. 

3.1.1 Mathematical Model 

DATARH program calculates the surface temperature, the surface heat flux and the transient heat 

transfer coefficient for heater rods by solving the “Inverse Heat Conduction Problem” (IHCP). 

The IHCP is basically the determination of the surface temperature, therefore the surface heat 

flux can be determined from the transient temperatures measured at an interior location of a 

heated structure. In the problem solved by DATARH, the initial temperature distribution is known. 

The IHCP is an ill-posed problem and in order to overcome the ill-posedness, several methods 

have been developed [9]. One method of solving IHCP problems is the Beck method which 

requires the knowledge of the initial wall temperature and proceeds sequentially. In this method, 

the equations are only solved for a few future times while the wall temperature and the wall heat 

flux is only taken up to the next time step, and the sequential procedure is started again by 

shifting it one time step further [9]. 

The finite difference approximation in implicit form of a one-dimensional heat conduction equation in 

cylindrical coordinates is typically [10]

where T(n) is the unknown temperature at node point n 

T'(n) is the known temperature at node point n. This is also the "initial value". 

r is the spatial variable. 

∆r is the spatial increment. 

∆θ is the time increment. 

Here, K, ρ, c are the thermal conductivity, density and specific heat, respectively. Their numerical 

values are computed at T'. If values at half intervals are required, they are evaluated at the 

average of two adjacent temperatures. 

q is the volumetric heat generation rate. 

N is the number of internals. Hence, there are N+1 node points. 

For n = 1, the node point is at the centerline of the rod, T(n-1)=T(n+1), since at this point the 

symmetry requires the flux be zero. At the point n=M, T(M) is the known measured temperature 

and finally, at the outer boundary point, n=N, T(n+1) is the desired wall temperature. If the heat 

conducting body is made up by composite material, the temperature at the interface can be 

handled by usual means, i.e. both the temperature and flux must be continuous. However, in this 

case, the spatial interval size, ∆r, would vary from region to region such that particular node 

points coincide with the material interfaces and T(M). 

Apply Equation (3-1) to node points n=1,2,...N and, combining the boundary condition T(0) = T(2) 

with the finite difference equation at n=1 to eliminate T(0), we have a set of N linear simultaneous 

equation with N unknown temperatures, T(n); n=1,..., N+1, n≠M. The solution of this set of 

equations define the temperature field at a given time step, θ. The transient solution can thus be 

obtained by repeating the same procedure with successive increment of ∆θ. 
13

The method outlined above is simple-minded in principle and straightforward in practice. 

Because of the implicit finite difference scheme, the stability of the computation is guaranteed. 

As long as reasonable increment sizes, ∆r and ∆θ, are chosen, acceptable numerical accuracy 

can be expected. 

It is noticed that if M=N+1, the inverse heat conduction problem is reduced to a more 

conventional type with a flux condition specified on one boundary (centerline) and a temperature 

condition specified on the other (wall). In this case, the coefficient matrix for the linear equations, 

as defined by Equation (3-1), is tri-diagonal. However, the presence of a known temperature, 

T(M), M≠N+1, in the linear set to replace the wall temperature, T(N+1), destroys the 

tri-diagonality and consequently complicates the solution procedure since for linear equations 

with a tri-diagonal coefficient matrix, the solution can be obtained by a time saving matrix 

resolution technique which is not applicable to any other form of matrix. 

Let us, for the time being, ignore the fact that T(M), M≠N+1, is known and assume that T(N+1) is 

known instead. The linear equation, written in the usual manner is: 

GNTNCFTJ      )1()(][ (3-6) 

where [J] is the tri-diagonal coefficient matrix defined by Equations (3-1) through (3-4).

Since all the quantities on the right hand side of Equation (3-10) are known, the wall temperature 

T(N+1), can be computed. The remaining temperature field can be obtained by repeated 

application of Equation (3-9). 

If the temperature measurement T(M) as a function of time is both accurate and frequent enough, 

the method outlined above would produce acceptable results. In practice, however, such 

accuracy and frequency as demanded by the numerical method is almost impossible to achieve. 

Any error in T(M), either due to instruments or due to interpretation, would be amplified in this 

numerical process. An error is usually propagative and oscillatory and results from a successive 

over and under correction of the heat balance as demanded by the governing heat conduction 

equation. 

Therefore, it is desirable to devise a numerical method such that the input error of T(M) could be 

damped during the subsequent computation steps. One such method is programmed in 

DATARH. It must be stressed that damping of input error can only improve the accuracy of the 

computed results by reducing the input error amplification. The inherent error due to inaccurate 

input data still remains. 

The basic principle of the method is to utilize the information of T(M) available over an open time 

span when the computation is just entering this time span. Let the parenthesized superscript 

denote a relative time step then the computation of )1( T

would not only involve an initial value

3.1.2 Structure of the Source Program DATARH.F 

This section briefly describes the structure of the source program. Detailed comments may be 

found within the body of the source program as well. The reader is advised that it will be helpful 

if a listing of the program DATARH.F is referenced as the remainder of this section is being read, 

since this will enhance the reader’s understanding of the description of the program structure that 

follows. 

All real variables used in the program have been declared double precision numbers, as 

indicated by the use of the implicit double precision (a-h, o-z) statement. The program reads 

two character variables, TITLE1 and RLOC, that may each be up to 15 alphanumeric characters 

in length. These are intended to be identifiers of a test case. No intermediate spaces may be 

present within each set of alphanumeric characters. However, each identifier may be of length 

less than 15 alphanumeric characters if desired. 

The program utilizes a number of data arrays, which may be identified by examining the 

dimension statements within the main program and sub-programs. It is important to note that 

some of these arrays have been declared to be of length 2000, while others have been declared 

to be of length 10 or 50. There are several arrays that have multiple dimensions; e.g., array ti is 

seen to be of dimension 10x10. These numerical figures are indicative of limits built into the 

program. 

The length 10,000 indicates that the current version of the program is capable of reading in up to 

a maximum of 10,000 sets of input data, each comprising time, clad temperature and power to 

the rod being analyzed. (See input file in1.dat described below.) It also indicates that the 

maximum number of points in time for which the program is capable of computing heat flux and 

heat transfer coefficient values is limited to 10,000. 

The length 10 indicates that the region between two adjacent conduction nodes may be divided 

into a maximum of 10 sub-regions. As seen by the data (r(i), i=1,5) statement, the program is 

capable of handling five outer conduction nodes and one implied conduction node at the 

rod-center, and hence five regions. Thus, the length 50 arises from the fact that the total 

number of sub-regions that may be handled by this version of the program is 10x5. 
17

The radial distance from the center of a heater rod to each outer conduction node is initialized by 

the data (r(i), i=1,5) statement. Currently, this statement contains radial data for RBHT heater 

rods, and values are in ft. 

The program reads input data via two input files. The file names are expected to be in1.dat and 

in2.dat. These files must exist at the time the executable is run. The required contents of 

these files are described in a section that follows. The program will write output data to a file by 

the name of out1.dat. This file will be created by the executable during a run, and a file by this 

name must not be present in the working directory at run-time. (If the output file from a previous 

run exists, it must either be deleted, or be renamed.) 

The program will terminate upon reaching the end of the input file in1.dat. As described in the 

section on input files that follows, the end of input data is signaled to the executable program by 

the use of characters END (case sensitive) in the input file in1.dat as input to character variable 

title1. 

Initializing the number of sub-regions within the region between a given pair of conduction nodes 

is accomplished by the array intv(i), i = 1 through 5. As discussed above, the maximum number 

of sub-regions within any region is limited to 10. The heater-rod length is set to be 3.66 m (12 ft) 

by means of variable tlength. 

After all input data has been read, and once the initialization of the conduction region dimensions 

and heater rod length has been completed, the program will write a summary of the input data to 

the output file. It is after this that the computational procedures begin. 

The first step is to convert the input time scale (array timer) so that the time of flood is treated as 

zero-time. This is accomplished by a do loop that causes the time of flood, tflood, to be 

subtracted from each time value (array timer) that was read by the program. Next, the number 

of data points that would be output by the program, jtime, is computed using the last value of 

input time, timer(nscan), the first value of input time, timer(1), and the value of dt (which is the 

time interval between results computed by the program). Note that nscan is the number of sets 

of input data points; see description of input file in1.dat below. Now, an array of time values at 

which results will be computed, array time, is computed. This too is accomplished by a do loop, 

and is performed by first setting time(1) equal to timer(1), and then successively adding the value 

of dt to the current value of time to get the next value of time. 

The next step is to compute an array of sink temperatures, Tsink. This array will have nscan 

number of values. It should be noted that the current version of the program treats the 

saturation temperature corresponding to the operating pressure as the sink temperature 

throughout the length of the heater rod. Thus, all values in array Tsink will numerically be the 

same. 

The program will now access an interpolation subroutine (a subroutine tbl in DATARH) to 

compute the saturation temperature, rod power, and the clad temperature at each value in array 

time (the time values at which results are desired). The value of sink temperature computed, 

Tsink, will be written to the output file at this time as well. 

Preparation of an array q that will contain volumetric heat generation rates at each value of array 

time is performed next. Each interpolated value of rod power (at a given value of time) is 

multiplied by the axial power factor, fax, and the radial power factor (if applicable), fp, and is 
18

divided by the total rod length. Then, each resulting value of q is converted to a volumetric heat 

generation rate in Btu/hr.ft2.s by means of appropriate conversion factors and rod dimensions. 

It should be noted that if the total power supplied to the rod that is being analyzed is input in file 

in2.dat (values of variable po11), then fp should be input as 1.0. (Zone power differences will 

be accounted for when total rod power is input.) It is important to note also that the value of fax 

is dependent on the axial height of the thermocouple from which clad temperatures have been 

obtained for input (values of variable tclad in file in2.dat). These have been calculated for each 

thermocouple location and for each rod in the RBHT rod bundle. 

The program investigates the curvature of the future three data points next. The subroutine that 

performs the inverse conduction calculation is called after this computation. Once the inverse 

conduction calculation is completed for all time values desired, values of heat flux and heat 

transfer coefficient at the rod surface are computed. These values along with the computed rod 

surface temperature at each time value are then written to the output file. The program will then 

continue onto the next case (if input data are present), or will terminate if the end of input data 

has been reached. 

It is important to note that the program limits the values of nscan and jtime to be 2000 at most. 

See statements if (nscan .gt. 2000) nscan=2000 and if(jtime .gt. 2000) jtime=2000 that appear 

within the source program. This is in accordance with the limitation in the dimensioning of some 

arrays, as described previously. It should also be noted that the maximum time up to which the 

program will compute results is limited to 2000 s after reflood. See statement 

tfinal=dmin1(2.0d+03, timer(nscan)) within the program. 

3.1.3 RBHT Rod Geometry and Materials 

The RBHT bundle and rod geometry is described in Section 2 of the report. Figure 2-3 shows 

the cross section of the RBHT bundle. The bundle has 45 heater rods and four unheated corner 

rods. The corner rods are used to support the bundle, grids and the thermocouple leads. The 

support rods are made from Inconel 600 tubing having a diameter of 9.525 mm (0.375 in.), a wall 

thickness of 2.108 mm (0.083 in.) and a form length of 3.96 m (156 in.). The heater rods are 

3.657 m (12 ft) in heated length with a skewed axial power profile, as shown in Figure 2-4, with 

the peak power located at 2.74 m (9 ft) elevation. The bundle has a uniform radial power 

distribution. The maximum to average power ratio (Pmax/Pavg) is 1.5, and the minimum to 

average power ratio (Pmin/Pavg) is 0.5 at both ends of the heated length. 

Figure 3-1 shows the description of the geometry for the RBHT heater rod geometry and 

dimensions. 

 
19

Figure 3-1: Geometry, Materials and Dimensions of RBHT Heater Rod. 

3.1.4 Required Input Files 

The program reads input data via two input files. The file names are expected to be in1.dat and 

in2.dat. These files must exist at the time the executable is run. 

File in1.dat should contain sets of input data arranged in lines, one line being required per reflood 

experiment analyzed. Each line must have values for the following input variables in the 

specified format, separated by one or more spaces: 
20

TITLE1 Character, A15 Identifier for each experimental run. 

RLOC Character, A15 Rod location/elevation. 

NSCAN Integer Number of data points per channel. 

FAX Real Axial power factor. 

FP Real Fraction of zone power to this rod. 

FKA Real Volumetric fraction of KANTHAL. 

PRES Real System pressure, psia. 

TFLOOD Real Time of flood, s. 

DT Real Desired time interval between successive values of heat flux and 

heat transfer coefficient calculated by this program, s. 

After the last set of values, a final additional line with 'END' (case sensitive) as the first two 

entries and zeros (in required format, real or integer) as remaining entries must be present. 

This signals end of input data to the executable program. 

File in2.dat should contain nscan sets of time, rod power and clad temperature values per line of 

data in file in1.dat. (The value of nscan appears as an input in file in1.dat.) One set of values 

must appear on one line, each value separated by at least one space. A description of the data 

required follows: 

timer Real Array of time values, s. 

po11 Real Rod power from decay power table at each TIMER value, kW. Note that the 

power input into the individual rod under consideration, corrected for decay, 

must be input here. 

tclad Real Clad temperature, deg. F, at each timer value. 

nscan Integer Number of data points per channel. Value is given as an input in file in1.dat 

The calculation of the axial power factors for the RBHT heater rods is given in Section 3.1.5. 

The sample input and output files from DATARH are given at the end of the section. 

3.1.5 Calculation of the Power Factor at Each Thermocouple Location 

Stern Lab measured the resistance of each heater rod filament beginning from the bottom of the 

heated length to the end of the heated length. The measurements were made over increments of 

one tenth of the length of the rod and the cumulative resistances were reported. Table 3-1 

shows a sample table of data from Stern Lab.

Figure 3-2. RBHT- Test Facility, Heater Rod Locations (Looking down from Top). 

Figure 3-2 shows the schematic of the RBHT test facility heater rod layout. The 7x7 bundle 

consists of 8 groups of rods as indicated by GR - # (group number), these are instrumented rods 

while GR-0 rods are un-instrumented. The PSP - # is the serial number of the rods as given by 

Stern Labs. 
22

The heater rod is composed of a series of resistances along the length. The power shape that is 

required is obtained by appropriately changing the pitch of the heater element. 

Using the data, the resistance for every incremental length (one tenth of the total length) is 

calculated by subtracting the value of resistance over the total length (0 to that axial location) 

from the previous value (0 to the previous axial location). This would give the resistance of the 

filament portion for that region (one-tenth of the total length). The incremental length over which 

the measurements are made is also calculated. This is a constant (14.28 in or 14.27 in). 

The axial power ratio is defined as the ratio of the incremental resistance for that incremental 

length over the incremental length to the total resistance of the rod over the total heated length. 

Using this definition, the axial power ratio over each incremental length is calculated. 

This is plotted as a function of length to get the power shape for each rod. Since the 

measurements provided by Stern labs was over every tenth of the heated length, these points 

were plotted at an average axial position (for example – for the length between 14.28 in and 

28.55 in, the incremental resistance and hence the power ratio over this span was plotted at a 

location of 21.415 in). Such a plot is shown in Figure 3-3, for Rod F4 (Stern lab heater number 2) 

Measurements from Stern labs were such that they bypassed the peak power location, meaning 

– the measurement was taken at 99.93 in and 114.20 in elevations. The peak power location was 

108 in. In order to calculate the power ratio at the peak power location and for any arbitrary 

location along the length of the heater rod, a straight line is fit for the power ratio calculated using 

the data points between 0 and 108 in. The equation for the power ratio is a function of length 

along the heater rod. Using this equation, the peak power ratio is calculated for each rod (i.e. the 

value of power factor is calculated at 108 in. location). This is then used along with the remaining 

calculated values of power ratio (for length beyond 108 in) and another such plot is made. An 

equation relating the power ratio and the heated length is obtained for the region beyond 108 in. 

Thus, for each heater rod, two plots are made, one for the length of the heater rod below the 

peak power location and the other beyond the peak power location to the end of the heated 

length. Using the equations for the power ratio as a function of axial position, the power ratio at 

any location along the heater rod is obtained. 

This procedure is followed for each rod with thermocouples and the power ratio for every 

thermocouple location is obtained. 

Table 3-2 shows a typical calculation for one rod (The resistances are values before swaging).

Figure 3-4 and Figure 3-5 show the plots of the power ratio as the function of length along the 

heater rod. Figure 3-4 is the plot from the beginning of the heated length to the peak power 

location (108 in.), while Figure 3-5 is the plot from the peak power location (108 in.) to the end of 

heated length. 

 

The values of the axial power factor for all the thermocouples used in the RBHT facility is shown 

in Table 3-3. The values of the axial power factors range from 0 to 1.5, which is the value at peak 

power location of 108 in. For example: RodB1_47.9 refers to the thermocouple at 47.9 in 

elevation for rod B1. These values are directly used in DATARH for the local rod heat flux and 

heat transfer coefficient calculations.

3.2. Subchannel Mean Bulk Fluid Temperature 

In order to calculate the local heat transfer coefficient in terms of the local bulk mean temperature 

of the flow, a method based upon the analogy of momentum and heat transfer was developed to 

correlate the local bulk mean temperature to the local subchannel centerline temperature, which 

was measured in the experiments [5]. Steam cooling data covering a wide range of Reynolds 

numbers were used to obtain a correlation factor for determining the local bulk mean 

temperature. 

The analogy between momentum and heat transfer is widely recognized for internal flows.

where T is the local temperature, u the local velocity, Tc the subchannel center temperature, uc

coordinate (r/ro)

For a given system pressure and bundle power, the local temperature profile, f(η), was measured 

at various axial locations for different Reynolds numbers. The Reynolds number is based on 

the local properties of steam evaluated at the local temperature. The correlation factor F was 

evaluated from the steam cooling test data as shown in Figure 3-6. Also shown in the figure are 

values of F obtained from the local velocity profiles reported in the literature for channel flows [6]. 

For turbulent flows, f(η) has been shown to satisfy a 1/n power-law relationship with n equal to 7 

over a wide range of Reynolds numbers. However, for Reynolds numbers between 2300 and 

5000, n has a value very close to 5. When the Reynolds number is greater than 106

, the value 

of n is close to 9. For Reynolds numbers below 2300, the flow becomes laminar and the 

correlation factor has a value of 1.5. 

The “F” method has been presented at an ANS meeting by Cheung et al. [5] and described in 

detail in the thesis work of McLaughlin [11]. The uncertainty in F depends, of course, on the 

uncertainty in the measured temperature profile using the steam probes as discussed in 

Appendix B. 
31

Figure 3-6. Variation of the Correlation Factor with the Reynolds Number. 

A method based upon momentum and heat transfer analogy has been successfully developed to 

correlate the local bulk mean temperature to the local subchannel centerline temperature by use 

of a correlation factor. The correlation factor is a function of the Reynolds number alone, which 

can be used to determine the local bulk mean temperature. 

Since the subchannel center temperature is used to calculate the mean bulk fluid temperature it 

is necessary to have a subchannel center temperature at every heater rod thermocouple location 

in which a heat transfer coefficient is to be calculated. To accomplish this, the thirteen 

subchannel center temperature measurements were plotted axially and a third order polynomial 

curve fit was generated such that the center temperature could be estimated at any elevation in 

the bundle. Figure 3-7 shows a sample axial plot of the subchannel centerline fluid temperature 

along with the third order data fit. 
32

3.3. Subchannel Reynolds Number 

Using the calculated mean bulk fluid temperature, the steam fluid properties were found and 

local subchannel Reynolds numbers were calculated along the axial length of the bundle. In 

order to calculate the local Reynolds number, the subchannel mass flow is calculated, assuming 

a uniform mass flow distribution of the steam through each subchannel: 

m

A

A

m

f

SC

SC   *  (3-31) 

where mSC  is the subchannel mass flow rate, m is the bundle mass flow rate, Af the bundle 

flow area, and ASC the subchannel flow area. 

The local Reynolds number is a function of the hydraulic diameter. In order to calculate the 

local Reynolds number in a subchannel, the local hydraulic diameter had to be calculated from 

the subchannel geometry as: 

SC

SC

H WP

A D *4 

 (3-32)

where DH is the subchannel hydraulic diameter, and WPSC the subchannel wetted perimeter. In 

this case the wetted perimeter is equal to the heated perimeter of the heater rods. 

The local Reynolds numbers were then calculated from Equation 3-33, where the properties for
33

the local viscosity of the steam are at the mean bulk temperature of the subchannel. That is: 

)( )Re( zA

Dm

z

SC

HSC



 

 (3-33) 

where Re(z) is the local subchannel Reynolds number and  the local viscosity. 

3.4. Heat Transfer Coefficient and Nusselt Number 

Heat transfer coefficients and resulting Nusselt numbers are calculated at all heater rod 

thermocouple locations within the inner 5x5 bundle, except for the corner rods. The rod outside 

wall temperature and local heat flux are calculated by DATARH and the mean bulk fluid 

temperature is found using the measured subchannel centerline vapor temperature and the heat 

transfer/momentum analogy as described in Section 3.2. With these three quantities known the 

heat transfer coefficient is found from: 

  )()(

)(" )( zTzTzq zh

w  b



 (3-34) 

where h(z) is the local heat transfer coefficient, q"(z) is the local heat flux, Tw(z) the local wall 

temperature, and Tb(z) the local mean bulk temperature. 

From the local heat transfer coefficient, the local Nusselt number can be calculated using the 

local vapor thermal conductivity of the steam evaluated at the mean bulk temperature. The 

expression for the Nusselt number becomes: 

)(

)( )( zkDzh zNu

v

H 

 (3-35) 

where Nu(z) is the local Nusselt number and kv(z) the local vapor thermal conductivity. 

3.5. Mixing Vane Grid Loss Coefficient 

Pressure drop measurements were made along bare bundle lengths (no grids within the 

pressure drop measurement span) and along spans that contained one or more grids using 

Differential Pressure (DP) cells. Grid loss coefficients were calculated across DP spans that 

contained one grid. 

The measured pressure drop across a span containing a spacer grid has two components; a 

single-phase frictional pressure drop caused by the bare bundle and a pressure drop related to 

the grid loss coefficient: 

Pmeasured bare  PP grid (3-36)

where ∆Pmeasured is the measured pressure drop across a span containing a spacer grid, ∆Pbare is 
34

the single-phase frictional pressure drop, and ∆Pgrid is the pressure drop caused by the grid itself. 

The single-phase pressure drop is related to the friction factor f by: 

H

bare D

fLV P

2

2   (3-37) 

where L is the DP span length, V the average velocity across the span, ρ the density evaluated at 

the average bulk fluid temperature across the DP span, and DH the bundle hydraulic diameter. 

The pressure drop created by the grid is a function of the grid loss coefficient (kgrid): 

 

2

2 Vk

P grid

grid

  (3-38) 

where ρ and V are the same as in Equation 3-37. 

Combining Equations 3-36 through 3-38, an expression for the grid loss coefficient can be found:

Review of Equation 3-39 shows that the grid loss coefficient is a function of the measured 

pressure drop, the DP span length, the bundle hydraulic diameter, the fluid density and velocity, 

as well as the single-phase friction factor. In this case the frictional pressure drop is calculated 

across the entire bundle length, including grids. 

The bundle hydraulic diameter is easily calculated and span length is known, however, 

determination of the average fluid density and velocity require an energy balance on the system. 

Knowing the inlet flow conditions and the bundle power, the fluid enthalpy as a function of bundle 

length is found from:

where P is the bundle power, m the inlet steam flow, P.F. the axial peaking factor shown in

bundle bulk fluid temperature can be determined:

C

hzh zT    ))(( )( (3-41) 

where Cp is the fluid specific heat. For this calculation Cp is assumed constant and is evaluated 

at the steam inlet temperature, and upper plenum pressure. 

Using Equations 3-40 and 3-41, the enthalpy and bulk steam temperature can be calculated at 

the ends of a DP span. The steam temperature is then averaged across the span and the 
35

average span fluid density is found for this temperature and the specified upper plenum 

pressure. 

With the average fluid density known for a given DP span, the average fluid velocity across that 

span is found by assuming a constant bundle flow rate: 

Af 

m V   (3-42) 

where Af is the bundle flow area and ρ the average fluid density across the DP span in question. 

3.5.1 Single-Phase Friction Factor 

As mentioned previously, DP measurements were made along bare bundle spans that do not 

contain a spacer grid. These measurements can be used with Equation 3-37 to determine 

single-phase friction factors:

DP f Hbare



  (3-43) 

where the variables are the same as in Equation 3-37 and the fluid density and velocity are 

averaged across the span and are derived from the energy balance described above. 

Figure 3-8 and Figure 3-9 below provide comparisons of the calculated friction factors from the 

RBHT data to several single-phase friction factor correlations. The Blasius correlation [7] was 

created for circular geometries and is valid for Reynolds numbers between 4000 and 105

. The 

Laminar correlation is taken from Moody [7] and is valid for Reynolds numbers below 2300. The 

correlation used by TRACE V4.160 [8] is a modification of the Churchill correlation and is used 

for all Reynolds numbers.

Review of Figure 3-8 and Figure 3-9 reveals that the majority of the RBHT single-phase friction 

factor data falls above the presented correlations. This is expected since the spacer grid acts to 

disrupt the boundary layer on the heater rods such that the flow must redevelop downstream of 

the grid, resulting in higher effective frictional losses. This behavior was also seen in the 

separate effects single-phase pressure drop experiments used to characterize the RBHT bundle. 

Due to the relatively large spread in the RBHT friction factor data and the fact that the calculated 

grid loss coefficients will be used to improve the models in TRACE, the single phase friction 

factors used for the grid loss coefficient calculation will be found from the correlation used by 

TRACE V4.160 instead of the relationship given in Equation(3-43). This is a modified Churchill

3.5.2 Grid Loss Coefficient Results 

Using the methodology described above, grid loss coefficients were calculated over a range of 

local Reynolds numbers spanning from approximately 800 – 2100. Each valid steady-state 

window allows a grid loss coefficient to be calculated for grids 2, 4, 5, and 6. A grid loss 

coefficient was not calculated for grid 1 because it is located close to the bundle inlet. Since the 

flow is not fully developed here the grid loss coefficient would be larger than expected. Loss 

coefficients were not calculated for grids 3 and 7 because these grids have moved, covering one 

of the DP taps which means the recorded pressure drop from these DP cells only reflects a 

partial grid loss. 

Grid loss coefficient results are plotted with respect to local Reynolds number and are shown in 

Figure 3-10 and Figure 3-11. The results are also available in Table 3-5 which lists the loss 

coefficient uncertainties as well.

4. SUMMARY 

Steam cooling experiments have been completed in the RBHT facility. The experiments were 

designed to collect quasi-steady state heat transfer data in which the working fluid was 

single-phase super-heated steam. The goal of the experiments was to collect the data 

necessary for the calculation of heat transfer coefficients that reflect the heat transfer 

enhancement caused by mixing vane grids. To accomplish this, heater rods were instrumented 

axially with thermocouples upstream and downstream of mixing vane grids. Steam 

temperatures were measured axially at subchannel centers and a method based on the 

momentum/heat transfer analogy was developed to relate the measured subchannel center 

temperature to the mean bulk steam temperature. 

The results of the heat transfer coefficient calculations are contained in Appendix A. The 

results are broken down by steady state window. From twelve experiments, thirty-five steady 

state windows have been deemed valid. Each steady state window has its own summary of 

conditions contained in Appendix A as well as critical instrument plots to show steady state has 

been reached. Heat transfer coefficients are calculated at every heater rod thermocouple 

location within the inner 5x5 bundle, excluding the corner rods. The results of an uncertainty 

analysis on the calculated heat transfer coefficients is also contained in the heat transfer tables. 

One should note that the heat transfer coefficients presented here are not “true” convective heat 

transfer coefficients since they were calculated using experimental measurements that reflect 

both convective and radiative heat transfer. 

Along with collecting the measurements used for the heat transfer coefficient calculations, 

detailed axial pressure drop measurements were also made. These pressure drop 

measurements were made across both bare bundle spans and across spans that contain a 

mixing vane grid. The bare bundle span measurements were used to calculate single-phase 

friction factors and the spans that contained a mixing vane grid were used to calculate grid loss 

coefficients. The results of these calculations are shown in Table 3-5 and the grid loss 

coefficients are tabulated with the local bundle Reynolds number and the results of a grid loss 

coefficient uncertainty analysis. The table shows that the uncertainty increases substantially as 

the flow rate decreases. The grid loss coefficients are also plotted as a function of local bundle 

Reynolds number as shown in Figure 3-10 and Figure 3-11.

presents the axial subchannel center steam temperature polynomial 

curve-fit equations used for data reduction, and notes any traversing 

operations made by the subchannel steam probe rakes. 

 Critical instrument plots – verifies steady state was reached and 

maintained for boundary conditions and selected heater rod and 

steam temperature measurements. The following experimental data 

is plotted over the steady state time window: 

1. inlet and exhaust steam flow rates 

2. inlet steam temperature 

3. bundle power 

4. upper plenum pressure 

5. selected steam probe rake temperatures 

6. selected heat rod temperatures 

7. axial subchannel center steam temperature profiles 

 Data tables – tabulations of the following: 

1. steam probe rake thermocouple positions and temperature 

measurements 

2. reduced data from DATARH, bulk steam temperature, heat 

transfer coefficient, and local Reynolds number calculations. 

Reduced heat transfer data is presented at all heater rod thermocouple locations 

within the inner 5x5 bundle, excluding the corner rods. That is, 21 rods totaling 130 

thermocouple locations. The results are organized by heat rod location and most 

heater rods have 8 thermocouples instrumented at various axial locations. Figure 

below provides the heat rod and subchannel identification diagram which indicates 

the location of heater rods within the bundle.

Appendix B. Single Point Uncertainty Analysis 

Single point uncertainty or replication analysis provides a method for predicting the uncertainty of 

a variable based on its component uncertainties. If one measures n quantities (or variables), x1, 

x2, ..., xn, and each of these quantities has a known experimental uncertainty associated with it, 

which shall be denoted by w, then the actual or true xi = measured xi  wxi, for each of the n 

measured xi quantities. Furthermore, unless otherwise specified, each of these uncertainties has 

a confidence level of 95 percent. Suppose now that some new variable, R, is a function of each 

of these measured quantities, i.e. R = R(x1, x2, ..., xn). The goal in replication analysis is to 

estimate the uncertainty in R to that same confidence level, i.e. actual or true R = calculated R 

wR, where wR is the uncertainty on variable R. To accomplish this, the root of the sum of the 

squares (RSS) method (A.1 Rabinovich) will be used, which defines wR as, 

 

 

 

(B-1) 

where wXi is the uncertainty of a specific variable and Xi

R



 is the sensitivity coefficient for that 

particular variable. 

B.1. Heat Transfer Coefficient 

In the case of the RBHT steam cooling tests, it is desired to calculate the overall RSS uncertainty 

associated with the experimental heat transfer coefficient, which is defined as,

TT bulkw

q h  

 (B-2) 

where Tw is the rod surface temperature and Tbulk is the mean bulk fluid temperature for a 

subchannel, defined as 

F

 )( 

 (B-3) 

where Tc is the measured subchannel centerline temperature and F is the Tbulk correlation factor. 

The local heat flux, q” is defined as 

 zf A

HRP

q  / " (B-4) 

where P is the measured bundle power, HR is the number of heater rods, A is the rod surface 
B-2

area, and f(z) is the axial power factor. 

Using Equations (B-1) through (B-4) along with the uncertainties of the measured quantities Tw, 

Tc, and bundle power it is possible to calculate the total uncertainty associated with the 

convective heat transfer coefficient. 

The uncertainty of the convective heat transfer coefficient will be calculated for test 3163-A, 

heater rod D3, at 2.24m elevation using the RSS replication analysis. 

Test 3163-A conditions: 

 Upper Plenum Pressure: 2.76 bar (40 psia) 

 Bundle power: 30 kW 

 Inlet Reynolds number: 6000 

 Steam flow 122.5 kg/hr 

 Heater Rods= 45 

Heater rod geometry: 

 Diameter: 9.5 mm Length: 3.66 m 

 Surface Area: 0.107m2 

Data for heater rod D3 at 2.24m (88.3 in) is given as: 

 Twi = 684.1 K Tc = 646.8 K 

F = 1.27 f(z) = 1.32 

Uncertainties from Table 8 are given as: 

wTw =  1.17 K wTc =  1.17 K 

 wP =  1290.35 W wD =  0.05 mm 

Throughout this sample calculation, the uncertainty in the heater rod length and the f(z) 

measurements has been neglected because it is sufficiently smaller than the largest uncertainty. 

Also, since there is no uncertainty in the measurement of the number of heater rods, this value 

does not contribute to the final value of the convection coefficient uncertainty. Finally, the 

uncertainty in the temperature difference between the inside wall of the heater rod cladding, 

where the thermocouple has been attached, and the outside surface temperature can be 

neglected. 

Although the measurements were taken from the inside of the heater rod, the uncertainty in 

moving this to the outer surface is negligible. This can be shown by first performing an 

uncertainty analysis on the following equation for Q, the total amount of heat transferred,

As can be seen, this value is nearly identical to that used in the initial calculation, showing that 

this temperature difference can be neglected. The uncertainty analysis on the convective heat 

transfer coefficient can now be performed, neglecting all terms with uncertainties that are 

sufficiently small.
B-5

Table 2: Total Probable Errors Used in Uncertainty Analysis 
B-6

To begin the uncertainty analysis of the convective heat transfer coefficient, the heat flux (q”) in 

Equation B-2 must first be determined because it is a function of various components each with 

their own uncertainty that must be found. The heat flux Equation is given as 

 zf A

where the axial power shape factor is given as:

 for elevations between 2.74 m and 3.66 m (z measured in meters) 

and 

zf z  5.0365.0)( (B-6b) 

 for elevations  2.74 m (z measured in meters). 

For an elevation of 2.24 m (88.3 in) where f(z) is 1.32, the heat flux is found to be

The uncertainty associated with the heat transfer coefficient is at 95 percent confidence level 

since all of the measured variables used to calculate the heat transfer coefficient were at a 95 

percent confidence level. With the uncertainty in the heat transfer coefficient known, the 

fractional uncertainty can be found to see how heat flux and the temperature difference affect the 

RSS uncertainty. 

Fractional uncertainty is simply defined as the uncertainty divided by the measured or calculated
