Contribution to Problem 6 using an upwind Euler solver with unstructured meshes

The goal of this paper is to discuss the application on critical problems encountered during reentry of space vehicles of an Euler flow solver developped in the past using unstructured meshes to handle equilibrium and/or nonequilibrium reactive flow simulations. Results in two dimensions for three test cases selected among those proposed around a double ellipse geometry at high Mach number and high angle of attack are presented.
