Abstract

In this Note, a model is proposed for the inviscid two-dimensional blunt-body flow in chemical non-equilibrium in the vicinity of the stagnation point. It is based on the use of the incompressible flow approximation for the density and velocity fields, and on a local linearization of the species convection equations about equilibrium values. A continuous solution is found that involves power laws whose derivatives are unbounded in practical situations. Thus, the analysis brings a rationale to explain why equilibrium conditions cannot be retrieved from the computation of such flow by a discrete method of conventional type.
