A hybrid kinetic-fluid model for solving the Vlasov-BGK equation

International audienceOur purpose is to derive a model for charged particles which combines a kinetic description of the fast prticles with a fluid description for the slow ones. This paper generalizes a similar approach where the hybrid approach was applied to gas dynamics. In this work, we consider the effect of a self-consistent electric field together with a more realistic collision operator of BGK type. A numerical scheme is constructed to simulate the hybrid Vlasov-Euler model, and various test cases are presented
