Abstract

Abstract

With the Euler equations and a two-step chemical reaction model, a numerical investigation of the wedge-induced oblique detonation wave (ODW) at low inflow Mach number is performed in this paper. Its stabilization process and stationary structure are studied in detail via numerical simulation. It is found that the upstream propagating of an attached ODW at low inflow Mach number is resulted from the effect of the high pressure region behind the induction region. In this condition, the ODW is always stable in the vicinity of the wedge tip. The length of the induction region is about one millimeter. When the ODW is triggered near the wedge tip, it will stay in its vicinity.
