Abstract
In the literature it was recently reported that for hypersonic reactive flow the shock
stand-off distance depends not only on a reaction rate parameter, but also on the
density ratio between shock and body. This is confirmed in this paper by a theoretical
approach which is based on the governing conservation equations. Reasonable simplifications
are introduced which for the frozen and equilibrium case allow an analytical
solution for the stand-off distance on spheres. The solution method is restricted to
this area since only the stand-off distance at the stagnation point is of interest. The
excellent agreement achieved for the frozen or non-reactive case with well-known solutions
gives evidence for the correctness of the solution method. For the equilibrium
case the solution obtained shows the same behaviour as a recent study which agrees
with experimental results and numerical simulations.
