A sequel to a rough Godunov scheme: application to real gases

We present here an approximate Riemann solver to compute Euler equations using real gas state laws. The scheme is based on an earlier proposition, called VFRoe, introduced by one of the authors. It makes use of non conservative variables in order to preserve numerically Riemann invariants through the contact discontinuity. Detailed investigation of actual rate of convergence of the scheme is reported. The study also includes a comparison with original VFRoe and Roe schemes. 7 2000 Elsevier Science Ltd.
