Experimental Investigation of a Planar Shock Wave Over a Double Wedge

Abstract

The research project consisted of three different phases: 1) An analytical investigation - During this phase the various reflection processes which can occur when a plane shock wave reflects over a double wedge were predicted. In addition, the transition boundaries between the various reflection processes were established. 2) an experimental investigation was conducted to verify the above mentioned analysis. Some other aspects regarding the reflection of a plane wedge over a double wedge were investigated experimentally. In particular, the wave configuration which is approached asymptotically should be mentioned. 3) A numerical code based on the TVD scheme was developed. The wave configurations as predicted by the numerical code were compared with those obtained experimentally and found to be in excellent agreement. This gave us some confidence in the numerical code and its predictions regarding the flow field generated during the reflection in general, and the pressure distribution along the wedge surface, in particular.
