A zero-dimensional Direct Simulation Monte Carlo (DSMC) model is developed for simulating reacting gas mixtures including state-to-state vibrational kinetics and simple bimolecular reactions. The method is applied to the simulation of three systems: translational relaxation of a hard sphere gas, vibrational relaxation of an anharmonic oscillator gas and dissociation in a simplified H-2-Xe system. In this last case, the role of translational non-equilibrium is shown to be important in affecting the dissociation kinetics. (C) 1998 Published by Elsevier Science B.V. All rights reserved.

Abstract
A zero-dimensional Direct Simulation Monte Carlo (DSMC) model is developed for simulating reacting gas mixtures including state-to-state vibrational kinetics and simple bimolecular reactions. The method is applied to the simulation of three systems: translational relaxation of a hard sphere gas, vibrational relaxation of an anharmonic oscillator gas and dissociation in a simplified H-2-Xe system. In this last case, the role of translational non-equilibrium is shown to be important in affecting the dissociation kinetics. (C) 1998 Published by Elsevier Science B.V.
