A relaxation system for the low-Mach limit of kinetic equations: Stability and higher order asymptotic preserving scheme
This work introduces a hyperbolic relaxation system designed for the simulation of kinetic equations in the low-Mach number limit. The methodology is built upon a micro-macro decomposition of the scaled BGK model, which reformulates the kinetic distribution function into a coupled system consisting of a macroscopic equ...
