Open-Source Direct Simulation Monte Carlo Chemistry Modeling for Hypersonic Flows [PDF]
AIAA Journal, 2015 An open source implementation of chemistry modelling for the direct simulation Monte Carlo (DSMC) method is presented. Following the recent work of Bird [1] an approach known as the quantum kinetic (Q-K) method has been adopted to describe chemical reactions in a 5-species air model using DSMC procedures based on microscopic gas information.
