An extension of Osher's Riemann solver for chemical and vibrational non equilibrium gas flows
Résumé
In this paper, we define an extension of Osher's Riemann solver adapted to chemically and vibrationally nonequilibrium flows. Some of its properties are discussed. We give 1D and 2D applications to illustrate the robustness and capability of this new solver. We show on numerical examples that the main properties of the Osher's solver are preserved ; in particular no entropy fix is needed even for hypersonics applications.
