The two-dimensional Euler equations coupled with a two-step chemical reaction model are solved. Four types of the reflection wave configuration of the CJ ODW are observed with the increase of the inflow Mach number Ma, i.e., overall Mach reflection (oMR), Mach reflection, regular reflection and non-reflection. The oMR is formed by the collision between the CJ ODW and the reflected shock wave of the oblique shock wave. At higher Ma, the oMR becomes a Mach reflection and then a regular reflection of the CJ ODW. At about Ma = 8.8, the reflected shock wave will be erased by the centered expansion wave and its reflected expansion wave.Read More
