Kinetic Approximation of a Boundary Value Problem for Conservation Laws

Denise Aregba-Driollet and Vuk Milisic

Abstract: We design numerical schemes for systems of conservation laws with boundary conditions. These schemes are based on relaxation approximations taking the form of discrete BGK models with kinetic boundary conditions. The resulting schemes are Riemann solver free and easily extendable to higher order in time or in space. For scalar equations convergence is proved. We show numerical examples, including solutions of Euler equations.
