Résumé

The kinetic modelling of chemically reacting gas mixtures represents a fundamental step in order to derive proper macroscopic description at hydrodynamic level. Useful model equations have been recently obtained following a consistent BGK approach. A common way to solve the BGK equations is based on the operator splitting, i.e. the solution in one time step is obtained by the sequence of collision-step and convection-step. Numerical approximation of such BGK equations for problems with axial symmetry is here adressed. Several results in the numerical resolution of the Riemann problem for gas mixtures, obtained with splitting methods of different orders, are presented. [DOI: 10.1685/CSC06004] About DOI
