Abstract
The problem of a hypersonic blunt body flow in two space dimensions is considered. The governing inhomogeneous Euler equations are given and the special treatment of calorically non-perfect gas in chemical non-equilibrium is described. The chemical model is given. The problem of the arising chemical boundary layer is discussed. Analytical and numerical investigations are used to analyse this boundary layer and to get error estimates for the numerical solution. Some modifications of the numerical method are given so that this boundary layer is indicated by the numerical solutions. An idea for a new boundary condition is proposed to obtain a better approximation of the wall pressure. Some two-dimensional test calculations are included. Show more
