Abstract:This technical note amends the chemical kinetics mechanism data for the thermal decomposition and combustion of gaseous nitroglycerin previously published by Chen and McQuaid in ARL-TR-9536. The updated mechanism data detailing the chemical kinetics as well as chemical species thermodynamic and transport properties are provided in formats compatible with commercial versions of CHEMKIN and the open-source Cantera chemical kinetics software packages. Multiple pressure-dependent reactions previously formulated using the Tsang and Herron “falloff” reaction formulae, unsupported by certain chemical kinetics software packages, were reformulated using the standard Troe or log-interpolation (PLOG) formulations. Details are provided concerning the falloff reaction conversions methods. Predicted linear burning rates using the updated mechanism are compared with experiments and predictions using the previous mechanism to validate the mechanism modifications.
