Asymptotic-Preserving (Ap) Schemes for Multiscale Kinetic Equations: a Unified Approach

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Kinetic equations have scalings, characterized by the mean free path, that lead to various different limiting behaviors, such as the Euler and Navier-Stokes approximations. Based on our previous studies on these issues, here we present a unified approach to develop asymptotic-preserving scheme for multiscale kinetic equations that allows the treatment of different length scales in a robust way. Our scheme works for both the rarefied and hydrodynamic (Euler and Navier-Stokes) regimes with a uniform accuracy. The idea is to use the even and odd-parity formulation. Our approach covers a large class of kinetic and transport equations.
