Abstract

A physical and mathematical model, computational algorithms, and numerical solution results are presented for a self-similar problem of supersonic flow of a multicomponent detonating gas past a flat wedge. The problem is considered in a two-dimensional, steady-state formulation, assuming that chemical reactions behind the shock wave occur in thermodynamic equilibrium. Two flow regimes are obtained: the first with an overcompressed detonation wave, the second with a Chapman-Jouguet detonation wave and an attached centered fan of Prandtl-Meyer rarefaction waves. Flow regimes for a combustible hydrogen-air mixture are studied for various flow parameters and wedge opening angles.

Keywords:

flow around a flat wedge; overcompressed detonation wave; detonating gas; Chapman-Jouguet detonation; rarefaction wave fan; thermodynamic equilibrium.
