Air, at a pressure of 60kPa and a temperature of -20°C, flows at Mach 2.5 over a wedge, which turns the flow through a 4° angle leading to the generation of an oblique shock wave. This oblique shock front impinges on a wall that turns away from the flow by 4° exactly at the point where the oblique shock front impinges on it, i.e., the wall has a sharp convex 4" comer at the point where the incident shock impinges on the wall. If the leading edge of the wedge is I metre above the wall, then how far behind this leading edge would the change in wall angle have to occur; calculate x?
