BGK models for inert mixtures: comparison and applications

Mathematical Physics 2021-02-26 v1 Numerical Analysis math.MP Numerical Analysis

Abstract

Consistent BGK models for inert mixtures are compared, first in their kinetic behavior and then versus the hydrodynamic limits that can be derived in different collision-dominated regimes. The comparison is carried out both analytically and numerically, for the latter using an asymptotic preserving semi-Lagrangian scheme for the BGK models. Application to the plane shock wave in a binary mixture of noble gases is also presented.
