Particle models of discharge plasmas in molecular gases

Abstract

We describe a mixed particle/continuum model for discharge plasmas in molecular gases developed by our group, which couples a particle description of the plasma phase with the diffusion/reaction kinetics of atoms and molecules in the gas phase. The model includes an improved treatment of ion kinetics, which fits some serious problems of multi time scale physical chemistry. The hydrogen plasma is considered as a test case. Results and computational costs are shortly discussed also in comparison with a different code. © Springer-Verlag Berlin Heidelberg 2004.
