| Résumé : | The moment method of Grad is used to derive macroscopic conservation equations for multicomponent plasmas for small and moderate Knudsen numbers, accounting for the electromagnetic field influence and thermal non-equilibrium. In the low Knudsen number limit, the equations derived are fully consistent with those obtained by means of the Chapman-Enskog method. In particular, we have retrieved the Kolesnikov effect coupling electrons and heavy particles in the case of the Boltzmann moment systems. A regularization procedure is used to achieve continuous shock structures at all Mach numbers. The equations are discretized by means of a finite-volume method. Preliminary results are presented for the simulation of a standing shockwave. |
