Wave decomposition in Riemann problems for heterogeneous media

Marek Brandner and Stanislav Míka

Abstract: This remark is devoted to the numerical solution of the equations for linear acoustics. We use the augmented formulation of conservation laws with spatially-varying flux function. The scheme is based on Roe's linearization for the augmented weakly hyperbolic system.
