Thermal Performance
In the Plate & Shell Heat Exchanger the heattransfer can best be described by a Dittus
Boelter type equation:
Nu = A(Re)n (Pr)m µuwx

Reported values of the constant andexponents are:A = 0.15 to 0.4

m = 0.3 to 0.45

N = 0.65 t0 0.85

x = 0.05 to 0.2

Where Nu = hdkRe = VdρµPr = Cpµk

D is the equivalent diameter defined in thecase of the plate heat exchanger as 2 x themean gap.
Typical velocities in plate heat exchangers
for water like fluids in turbulent flow arenormally in the range of 0.3 to 0.9 m/s buttrue velocities in certain regions will behigher due to the effect of the corrugations.
All heat transfer and pressure drop
relationships are, however, based on either avelocity calculation from the average plate
gap or on the flow rate per passage.

To achieve these high coefficients it isnecessary to expend energy. With the Plate& Shell unit, the friction factors normallyencountered are in the range of 10 to
400times those inside a tube for the same
Reynolds number. However, nominal
velocities are low and plate lengths do not
exceed 1m so that the term V2L
2g
in the same pressure drop equation is verymuch smaller than one would normallyencounter in tubulars. In addition, single
pass operation will achieve most duties sothat the pressure drop is efficiently used and
not wasted on losses due to flow directionchanges.
The friction factor is correlated with anequation:δp = f.Lρ v2
2g.d
where

f= B
Rey

Where y varies from 0.1 to 0.4 according to
the plate and B is a constant characteristic of
the plate. If the overall heat transfer
equation H = USδT is used to calculate theheat duty, it is necessary to know the overall
coefficient U (sometimes known as the Kfactor), the surface area S and the mean
temperature difference δT.

One particular important feature of the Plate& Shell is that the turbulence induced by thetroughs reduces the Reynolds number atwhich the flow becomes lamina. If thecharacteristic length dimension in the
Reynolds number is taken as twice theaverage gap between the plates, the Re
number at which the flow becomes laminar
varies from about 100 to 400 according toplate geometry used.
Vahterus Plate & Shell® Heat Exchangers I 2010

The overall coefficient U can be calculated
from
1 = rfh + rtc + rw + rdh + rdc
U
The values of rfh and rfc (the film resistances
for the hot and cold fluids respectively) can
be calculated from the Dittus Boelter
equations previously described and the wall
metal resistance rw can be calculated fromthe average metal thickness and thermal
conductivity. The fouling resistances of the
hot and cold fluids rdh and rdc are often basedon experience but a more detailed discussionof this is available separately.
The value taken for S is the developed area
after pressing. That is the total area available
for heat transfer and, due to thecorrugations, will be greater than the
projected area of the plate.
The value of δT is calculated from thelogarithmic mean temperature difference
multiplied by a correction factor. With
single pass operation, this factor is about 1
for counter flow operation. This can be asignificant difference compared to tubulars
where the fluids tend to operate in crossflow
where the factor can be as low as 0.6.

Geometry.

Part of the heat transfer equation to determine the amount of surface
area required to perform a given duty is in establishing the turbulencecreated, which in turn helps us establish the overall heat transfer
coefficient.
Shell & Tubes utilise a very poor geometry for this –fluid flowing
through round tubes is not very effective in producing turbulence.
Similarly, fluid flowing over a bank of tubes on the shell side of theexchanger is an inefficient way of producing turbulence. Therefore, theresultant overall heat transfer coefficients are correspondingly poor.
Plate & Shell Heat Exchangers employ a corrugated plate surface,which create thin streams in the fluid, which are constantly changing
direction. This in turn leads to high turbulence and thus, high heattransfer coefficients.

Efficient use of Heat Transfer Surface

Within the Shell side of a Shell & Tube heat exchanger there are deadspots, areas of low velocity and areas for fluid to bypass the tubes – allthis contributes to reducing the overall effectiveness of the exchanger.

In contrast, the Plate & Shell Heat Exchanger has no dead spots, all thesurface area is utilised in the heat transfer process, and there is no
possibility of fluid bypassing the heat transfer surfaces. This, again,
ensures high heat transfer coefficients.

Vahterus Plate & Shell® Heat Exchangers I 2010

3. Temperature Difference
To achieve a high level of effectiveness it is important to make the best use of thedriving force of hot to cold. We all refer to this as the “Log Mean Temperature
Difference” (LMTD). To achieve the full use of the LMTD it is necessary to have thefluids flowing in opposite directions in adjacent passages.
This cannot be achieved by a Shell & Tube design as by its very nature ofconstruction the fluids on opposing sides of the exchanger flow at 90 degrees toeach other. This is called “cross flow” and can de-rate the potential effect of the
LMTD by as much 35%.
Compare this with a Plate & Shell heat exchanger, which has fluids flowing in
opposing directions (counter flow).
