The problem considered in the present study is that of transition from Mach to regular reflection of a shock wave over a concave corner. For analytical purposes, it is assumed that a circular cylindrical concave surface can be represented by a sequence of infinitesimal wedges. The calculated results show that the critical transition angle of incidence of a shock wave increases with an increasing initial angle of the concave surface and decreases with an increasing strength of the incident shock wave. These values are smaller than those predicted by the two shock theory. To verify the validity of the present calculation, an experimental investigation was performed using a concave corner model which was composed of two straight walls, and it was confirmed that the experimental results agreed well with those of the present calculation.
