Study on Mach Reflection and Mach Configuration

Shock reflection is a fundamental phenomenon in studying compressible flow. Since Ernst Mach first studied the reflection phenomena of shock waves in 1878 [6] great amount of research works on such phenomena, mainly experiments and computations, was proceeded. In gas dynamics when a shock wave meets an obstacle in its propagation process the shock reflection occurs generally. There are various different shock reflection patterns, depending on the shape of the obstacle, the angle of the incident shock front hitting the obstacle, as well as the parameters of the incident shock.
