ABSTRAKT

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. In particular, we focus on hydrogen plasma, in view of the interesting negative ion kinetics. The model includes an improved treatment of ion kinetics, which incorporates original solutions for specific problems of multiple time scale kinetics. Results obtained for a parallel plate, radio frequency discharge considered as a test case are discussed, also in comparison with fluid code results.
