Classification of shock wave reflections from a wedge. Part 2: Experimental and numerical simulations of different types of Mach reflections

Shadowgraph images of different types of irregular reflections that illustrate the suggested classification are presented. The complex forms of the Mach reflection are studied by numerical simulation at various initial parameters. Emphasis is on the near-wall behavior of the contact discontinuity in the main Mach configuration and on intersection between contact discontinuities. Analysis shows that, if an incident shock wave is strong, interaction of the shock wave with an infinite wedge is a nonstationary process.
