A Finite Volume Solver for Radiation Hydrodynamics in the Non Equilibrium Diffusion Limit

Abstract

We derive an Implicit Explicit finite volume scheme for the computation of radiation hydrodynamics. The convective part is handled through a classical upwind method while the reactive and diffusive parts are discretized thanks to a centered scheme. These results are compared to semi-analytic solutions obtained by Lowrie and Edwards [10]. © Springer-Verlag Berlin Heidelberg 2011.
