Introduction
When a moving shock wave encounters a convex cylinder, reflects from it regularly, and propagates further, at one particular shock position corresponding to the so-called sonic point the flow on the cylinder’s surface, just behind the reflected shock becomes sonic with respect to the moving reflection point. The sonic point is prominent in the theory of regular-to-Mach reflection transition as one of its possible criteria [1]. When the flow behind the reflected shock wave becomes sonic, downstream perturbations can reach the reflection point and, supposedly,may cause the regular-to-Mach reflection transition.
