13. SUPPLEMENTARY NOTES 

14. ABSTRACT 

Between 2003 and 2005, a detailed, multistep, finite-rate chemical kinetics mechanism was developed to provide a basis for 

modeling monomethylhydrazine-red fuming nitric acid (MMH-RFNA) ignition and combustion chemistry. It was assembled 

almost entirely from reaction rate expressions and thermochemical data developed and validated for other combustion systems. 

When the mechanism’s development was discontinued in 2005, it was composed of rate expressions for 513 reactions and 

involved 81 species. A lack of relevant experimental data limited the extent to which it could be validated as a whole. 

Nevertheless, when a subset of the mechanism was employed as a submodel for a computational fluid dynamics (CFD) model 

of an impinging stream vortex engine (ISVE) fueled with MMH-RFNA, the CFD model produced simulations whose 

calculations for chamber pressure and thrust well-reproduced ISVE test firing data. As such, the mechanism is considered to 

have a reasonable measure of validity and, thus, to be a good starting point for obtaining more refined MMH-RFNA 

mechanisms. This report discusses the mechanism’s development and provides the rate expressions and thermochemical data 

that compose it. The sources of the rate expressions and thermochemical data are also provided.

1. Introduction 

This report discusses a detailed, finite-rate, chemical kinetics mechanism that was developed to 

provide a basis for modeling the ignition and combustion chemistry of systems fueled with 

monomethylhydrazine (MMH) and red fuming nitric acid (RFNA). Pursued between 2003 and 

2005, the effort to develop a mechanism for this hypergolic (bipropellant) combination arose in 

conjunction with an effort to develop a computational fluid dynamics (CFD) model capable of 

simulating the combustion chamber dynamics of the U.S. Army Aviation and Missile Research, 

Development, and Engineering Center’s (AMRDEC’s) impinging stream vortex engine (ISVE). 

Conceived in the 1960s, but not developed in earnest until the 1990s, the first ISVEs built and 

tested by AMRDEC were fueled with MMH and inhibited RFNA (IRFNA) (Michaels and 

Wilson, 1995). Although hypergolic rocket motors that employ MMH and IRFNA in 

combination with one another do not appear to ever have been fielded, MMH and IRFNA are 

standard rocket propellants that, both individually and when mixed, have properties that make 

MMH-IRFNA a natural candidate for tactical missile applications. And AMRDEC was able to 

fly an ISVE fueled with the pair, confirming its utility for the application. 

The CFD model ARL developed to simulate the ISVE’s combustion chamber dynamics was 

derived from the ARL-NSRG3 code (Nusca, 2002). Of the many issues addressed in developing 

the code for modeling such systems, one was the specification of a representation of the reaction 

kinetics underlying MMH-IRFNA’s ignition and combustion. As discussed in detail elsewhere 

(Nusca and Michaels, 2003), an empirical one-step reaction (mechanism) was proposed and 

employed for the earliest version of the model. By adjusting the rate constant of the reaction, it 

was possible to get the CFD model to produce simulations whose calculations of chamber 

pressures at steady-state operating conditions matched those observed in test stand firings. 

However, pressure transients associated with the ignition phase of the ballistic cycle were not 

well reproduced, and there were questions about how well other results (such as predictions for 

species concentrations) corresponded to those occurring in the actual motor. Thus, a better 

representation of the bipropellant’s chemical kinetics was considered needed, and the 

development of a detailed, multistep, finite-rate MMH-RFNA (vs. MMH-IRFNA) mechanism 

was undertaken.*

 

An overview of the development of the MMH-RFNA mechanism has been provided previously 

(McQuaid et al., 2005). Briefly, its construction began in 2003 from sources that included (1) a 

mechanism that had been assembled to model the combustion of double-base (nitrate ester) and 

 *Note: RFNA is a mixture of HNO3, NO2, and H2O. To inhibit RFNA’s ability to corrode storage containers, a very small 

amount of HF is added. The resulting mixture is called IRFNA. Because HF is present in such small amounts, its influence in 

MMH-IRFNA ignition and combustion processes is suspected to be negligible. Therefore, reactions with fluorine-containing 

species were not included in the mechanism. Without such reactions, the set is more properly called an MMH-RFNA 

mechanism.

nitramine propellants (Vanderhoff et al., 1992; Anderson et al., 1995), (2) a mechanism that was 

developed to model the combustion of natural gas (Smith et al., 2003), (3) rate expressions for 

reactions involving HNO3, NO3, N2O4 (NTO), and hydrocarbon-NOx moieties that were 

identified via a literature search performed specifically for the MMH-RFNA mechanism 

development effort, and (4) mechanisms Catoire and coworkers developed to model the ignition 

and combustion of MMH-O2 and MMH-NTO systems (Catoire et al., 1998; Catoire et al., 2004). 

Thermochemical parameters recommended by Catoire and Swihart (2002) for compounds 

expected to play a role in MMH ignition and combustion were also included. Additional 

development led to the modification of thermochemical parameters for some species, the 

inclusion of a CH3NHNH2 + HNO3 complexation reaction (McQuaid et al., 2005), and the 

inclusion of a set of reactions Glarborg and coworkers (1999) developed and employed to model 

the decomposition of nitromethane. 

When the effort to develop the MMH-RFNA mechanism was discontinued in 2005, the 

mechanism was composed of rate expressions and thermochemical parameters for 513 

elementary reactions and 81 species. From a scientific standpoint, additional investigations of 

other aspects of the mechanism were (and still are) considered warranted (McQuaid et al., 2005), 

but the expenditure of additional ARL (in-house) resources for such an effort could not be 

justified. For one, when the CFD model of the ISVE employed a (reduced) chemical kinetics 

submodel derived from the (full) mechanism, its predictions for the combustion chamber 

pressure and thrust profiles of ISVE firings agreed with experimental data over the entire 

ballistic cycle (Nusca and Michaels, 2004; Nusca et al., 2008). In addition, AMRDEC had come 

to the conclusion that the risks posed by MMH to human health and the environment would 

make MMH-IRFNA untenable for Army applications for which an ISVE might be utilized. 

Therefore, AMRDEC started to predicate its ISVE development program on the use of MMH 

alternatives. With that shift, ARL’s basis for developing the mechanism lapsed, and no other 

Army application for which MMH-RFNA might be used has become apparent since then. With 

its development discontinued, the 513 reaction-81 species mechanism has come to be viewed as 

a benchmark. 

For several reasons, ARL has not previously published any MMH-RFNA chemical kinetics 

mechanism in its entirety. When MMH-IRFNA was the primary candidate for fueling ISVEs 

and the mechanism was an integral aspect of the ISVE development effort, it was recommended 

that the mechanism’s distribution be extremely limited. The shift to MMH-alternatives for the 

ISVE application reduced the need to restrict the mechanism’s distribution, but then there was no 

particular motivation for undertaking the effort required to produce a reference-quality document 

for that purpose. Because the primary validation of the mechanism (as a whole) was that a CFD 

model with a chemical kinetics submodel derived from it produced simulations whose 

calculations for combustion chamber pressure and thrust agreed with data from MMH-IRFNA 

fueled rocket motor firings, it would not meet the standards required for publication in a refereed 

journal. Justification for undertaking the effort to provide it in an ARL technical report was also 
3

lacking. That changed, however, when the U.S. Department of Defense decided to fund two 

multi university research initiatives (MURIs) on gelled hypergolic propellant spray combustion. 

Seeking to jump-start their efforts, the MURI groups requested the mechanism. Concluding that 

the potential benefits of its distribution outweighed the potential negative consequences that can 

attend the release of a mechanism that has not been rigorously validated and published, ARL 

distributed it to the groups in October 2008. Consequently, it was considered that a report that 

provides and discusses the mechanism would be useful for assessing and discussing any 

proposed refinements. This report is intended to serve that purpose. 

In addition, it is anticipated that the MURI groups will employ various methods for reducing 

their chemical kinetics mechanisms to produce submodels for CFD codes. As such, a common 

(benchmark) mechanism to which the reduction methods can be applied would be helpful in 

evaluating their relative merit. (The mechanism had previously been provided to an AerodynePrinceton Small Business Technology Transfer [STTR] team for that purpose.) Given its 

distribution, the mechanism provided here can serve that role as well. 

2. Discussion 

The MMH-RFNA mechanism that was provided to the MURI groups and the AerodynePrinceton STTR team is given in the appendix. As mentioned in the Introduction, the 

mechanism contains 513 elementary reactions, and except for one case, the rate expressions for 

the reactions were obtained from open-literature sources. Thermochemical parameters for the 

species in the mechanism were, likewise, largely obtained from the open literature. In some 

cases, however, they were developed in-house (McQuaid et al., 2005). In most cases, sets of 

reactions were taken from mechanisms that had been developed and validated for other systems. 

This section identifies and discusses the primary sources of the data and the basis of their 

validation for the application for which they were developed. The numbering of the reactions in 

this section references table A-2 in the appendix. 

2.1 Reactions 1–205 

Reactions 1–205 come from a “dark-zone” (DZ) chemical kinetics mechanism that Anderson and 

coworkers assembled for modeling the combustion of double-base (nitrate ester) and nitramine 

(gun) propellants (Anderson et al., 1995; Vanderhoff et al., 1992). Because the DZs of flames 

produced by double-base propellant strands (burning in cigarette fashion at pressures from 1 to 

30 atm) contain large quantities of H2, H2O, NO, N2, CO, and CO2, Anderson et al. (1995) paid 

considerable attention to identifying a reaction set that could model systems in which these small 

molecules play prominent roles. Similarly, results from strand burner experiments with 
4

nitramine-containing propellants prompted the inclusion of reactions to account for the 

production and decomposition of HCN and N2O. Agreement between predictions based on the 

DZ mechanism and results from strand burner experiments was good, establishing the 

mechanism’s validity for that application. 

Since H2, H2O, NO, N2, CO, CO2, HCN, and N2O are all, to varying degrees, expected in MMHIRFNA combustion, it was natural to include reactions from the DZ mechanism in the MMHRFNA mechanism. The extracted subset comprises a core of small molecule reactions and 

species thermochemical parameters that ARL routinely employs in its development of 

mechanisms for the study of propellant combustion and NOx emission. Initially developed from 

a critical review of the literature, this core has since been frequently updated. The bulk of the 

thermochemical parameters for the species in these reactions was obtained from a database 

developed at Sandia National Laboratories (Kee et al., 1987). An extensive ARL report that 

critically reviews the literature on DZ chemistry and provides comparisons between 

experimentally-based observations and mechanism-based modeling results is being written by 

Anderson and coworkers (Anderson et al., report in preparation). Full documentation of sources 

for the most recent version of the DZ mechanism will be provided therein. The data for reactions 

common to the MMH-RFNA mechanism and the most recent version of the DZ mechanism are 

mostly the same. 

2.2 Reactions 206–351 and 413–427 

Reactions 206–351 and 413–427 were taken from GRI-Mech 3.0 (Smith et al., 2009). GRIMech 3.0 contains 325 elementary reactions and involves 53 species. It was developed to model 

the combustion of natural gas and has been extensively validated (as a whole) for that 

application. Because natural gas is composed primarily of methane, reactions involving small 

hydrocarbon species are pertinent to its combustion, and the reaction set in GRI-Mech 3.0 

reflects this. Because MMH has a methyl (CH3) group, MMH-RFNA combustion was 

considered likely to involve similar reactions. Most of the 177 reactions that were extracted 

from GRI-Mech 3.0 involve CxHyOz species reacting with atoms or diatoms. Some reactions 

with nitrogen-containing molecules are also present in this (sub)set. Most molecules in reactions 

206–351 and 413–427 contain only one or two heavy atoms (i.e., C, N, or O), and none contain 

more than three. Thermochemical parameters for the molecules involved in these reactions are 

primarily from Kee et al. (1987). 

2.3 Reactions 352–412 

Reactions 352–412 were assembled from a literature search focused on identifying rate 

expressions for elementary reactions that would be relevant for modeling the chemistry of 

hydrocarbons oxidized by HNO3 and NO2. Some of the expressions were extracted from a 

chemical kinetics mechanism developed to model the combustion of ammonium dinitramide 

(Anderson, 2001). The thermochemical parameters for the molecules in these reactions are 

primarily from Kee et al. (1987). 
5

2.4 Reactions 428–443 

Reactions 428–443 are small molecule reactions pertinent to hydrocarbon-NOx, hydrocarbonNxHy, and HCN decomposition chemistry. Their rate expressions were identified through a 

literature search that was performed subsequent to assembling the characterizations of the 

reactions discussed in sections 2.1, 2.2, and 2.3. The thermochemical parameters for the 

molecules in these reactions are primarily from Kee et al. (1987). 

2.5 Reactions 444–496 

The rate expressions for reactions 444–496 were extracted from mechanisms Catoire and 

coworkers developed to model MMH-O2 and MMH-NTO systems (Catoire et al., 1998, 2004). 

When employed with CHEMKIN to simulate the response of MMH-O2-Ar mixtures subject to 

(reflected) shock waves at various pressures and temperatures, the MMH-O2 mechanism yielded 

ignition delay times observed experimentally. Similarly, when employed with CHEMKIN to 

simulate MMH-NTO chemical ignition delays for mixtures at various stoichiometries, 

temperatures, and pressures, the MMH-NTO mechanism was found to yield results comparable 

to those predicted by the theory of thermal explosions. Thermochemical parameters for 

molecules unique to these two mechanisms were obtained from Catoire and Swihart (2002). 

However, the thermochemical parameters published for CH3N(NH2)NO2 and CH3N(NH2)ONO 

were found to be unreasonable and modified (McQuaid et al., 2005). Results from quantum 

chemistry calculations suggest that the activation energy that Catoire et al. (2004) specified for 

H-atom abstraction from MMH by NO2 is slightly low (McQuaid and Ishikawa, 2006), but it was 

not changed. 

2.6 Reaction 497 

In developing the MMH-RFNA mechanism, early versions did not produce any significant 

temperature rise when employed (with CHEMKIN) to simulate the evolution of homogenous 

MMH-RFNA mixtures initially at temperatures below 600 K. Since such mixtures are known to 

ignite at temperatures less than 300 K, an explanation was sought. The only possibility that was 

really considered was the early versions’ lack of a direct reaction between MMH and HNO3. 

Without such a reaction, HNO3 acts as a heat sink at temperatures below which it rapidly 

dissociates to OH and NO2, soaking up energy from other exothermic processes that have the 

potential to bootstrap the mixture to a temperature at which ignition will occur. 

To address this issue, reaction 497, a complexation reaction between MMH and HNO3, was 

added. Given the chemical nature/structure of MMH and HNO3 (i.e., a base and an acid, 

respectively), it was clear that a hydrogen bond could form between the two and that the reaction 

would be strongly exothermic. This was quantified by quantum chemistry calculations. 

Thermochemical parameters for the MMH-HNO3 complex (named NAMMH in the mechanism) 

were derived from a B3LYP/6-31+G(d,p) model. Though this model is not generally 
6

considered sufficient for such purposes, it was considered adequate for obtaining estimates for 

checking the hypothesized importance of the reaction as an ignition enabler. In the same vein, 

rate constants for the reaction were specified based simply on the assumption that there was no 

barrier to the formation of the complex and that it proceeded at a high-pressure limit rate. 

With reaction 497 incorporated into the mechanism, ignition-like behavior is observed in 

simulations of homogenous MMH-RFNA mixtures initially at temperatures as low as 300 K, 

corroborating the hypothesized importance of a MMH-HNO3 complexation reaction for the 

initiation MMH-RFNA mixtures at low temperatures. However, given the level of theory 

employed to estimate the thermochemical parameters and rate coefficients that characterize it, it 

is likely that they can be improved. There is also a possibility that rather than simply 

dissociating back to the reactants, bimolecular reactions of the complex can occur, e.g., with H, 

OH, or NO2. Clearly, the mechanism could benefit from further refinement in these areas. 

2.7 Reactions 498–513 

Reactions 498–513 were taken from a mechanism developed to model shock-induced 

decomposition of dilute CH3NO2-Ar mixtures (Glarborg et al., 1999). Because CH3 is a likely 

product of MMH’s decomposition and NO2 is present in RFNA, CH3NO2 could possibly form at 

low temperatures from CH3 + NO2 recombination, thus making the set’s reactions pertinent to 

MMH-RFNA ignition and combustion. The thermochemical parameters for the molecules in 

this set are primarily from Kee et al. (1987). 

3. Summary 

Between 2003 and 2005, a detailed, multistep, finite-rate chemical kinetics mechanism for 

modeling the ignition and combustion of systems fueled with MMH-RFNA was developed. The 

mechanism was assembled from reaction rate expressions and thermochemical data that, 

individually or in sets, were validated for other combustion systems. A lack of relevant 

experimental data limited the extent to which the mechanism could be validated as a whole, and 

its development was discontinued prior to resolving some issues that had been raised. 

Nevertheless, when a subset of the mechanism was employed as a submodel for a CFD model of 

AMRDEC’s ISVE, the CFD model produced simulations whose results for chamber pressure 

and thrust agreed with ISVE test firing data. As such, the mechanism is considered to have a 

reasonable measure of validity and should therefore be useful as a starting point for obtaining 

more refined MMH-RFNA (or MMH-IRFNA) mechanisms.

Appendix. Mechanism Data Tables 

The monomethylhydrazine-red fuming nitric acid (MMH-RFNA) mechanism discussed in this 

report comprises thermochemical parameters and rate expressions for 81 species and 513 

elementary reactions. Thermochemical parameters are given in table A-1, and the rate 

expressions are given in table A-2. The thermochemical parameters include (1) heat of 

formation at 298 K [Hf(298)], (2) entropy at 298 K [S(298 K)], and (3) the constant pressure heat 

capacity [CP(T)] as a function of temperature [T]. 

For reactions whose rates (k) are not a function of pressure, the Arrhenius expression k = 

ATb

exp(-E/RT) calculates the rate at a specified temperature from the given frequency factor 

(A), temperature exponent (b), activation energy (E), and the ideal gas constant (R). For 

reactions involving a generalized collider species (M) (and whose rates are therefore pressure 

dependent), an effective collider concentration (CM) is calculated from the expression CM = 

[p/(RT)]Σi Xiηi, where p is the pressure, Xi is the mole fraction, and ηi is the collider efficiency 

of species i. Collider efficiencies are assumed to be 1.0 unless otherwise specified. Then, one of 

three expressions is employed for the rate calculation. If “T&H VALUE(S)” is specified, the 

Tsang and Herron1 form is used and constants for that form are given, i.e., a0 and (possibly) a1. 

(The standard CHEMKIN interpreter and the subroutine for computing rates have to be modified 

to perform this computation.) If “TROE centering” is specified, the TROE form is employed, 

and its parameters are given. If no special form is specified, the Lindemann form is employed. 

Descriptions of the latter two expression types may be found in the CHEMKIN manual.2 For 

reactions that appear in the mechanism more than once, the phrase “declared duplicate reaction” 

is inserted, and the rate is computed from the sum of the two specified expressions. (The two
