Abstract
We focus on the computation of a hyperbolic system describing a multicomponent turbulent flow for isentropic gases, using an exact Riemann solver. This method is very robust, but costly. Thus, we introduce two approximate upwinding schemes: a Godunov scheme called VFRoe and a Rusanov scheme. The Rusanov scheme always ensures positive values for mass, concentration and turbulent kinetic energy, but generates less accurate results. We show some one- and two-dimensional computations and compare these three resolution methods.
