Abstract
Shock wave reflection from concave cylindrical and elliptical wedges is numerically studied. The model of a polyhedron inscribed into a circular cylinder is used to elucidate the mechanism of formation of reflection configurations in unsteady flows. This numerical simulation gives a clear indication of how the initial incident shock wave “receives information” from the reflecting surface. Flow features resulting from shock reflection off smooth, concave wedges are considered for different shapes of the reflecting surface. It is found that the evolution of the shock wave reflection configuration is determined by the shape of the reflecting wedge. It is shown that the Mach to regular reflection (MR $$\rightarrow $$ RR) transition angles are different for different reflecting surfaces with the same incident shock Mach number.
