Abstract
A consistent BGK-type approach to reacting gas mixtures, according to Boltzmann-like kinetics for a bimolecular reversible chemical reaction has been recently introduced. In this paper we apply a numerical strategy based on time splitting techniques to simulate the reactive BGK equations. These techniques have the advantage of simplifying the problem by treating separately the convection step and collision step. Numerical results of the time-dependent Riemann problem for the reactive BGK system are presented.
