Simplified Combustion Modeling of Double Base Propellant: Gas Phase Chain Reaction Vs. Thermal Decomposition

摘要

Simplified combustion modeling of nitrocellulose (NC), nitroglycerin (NG) double base propellant is considered. Two models with simple but rational chemistry are compared: the classical thermal decomposition, high gas activation energy (E_G/RT1) Denison-Baum-Williams (DBW) model, and a new chain reaction, low gas activation energy (E_g/RT1) model recently proposed by Ward, Son, and Brewster (WSB).
