000013862 520__ $$2eng$$aShock wave reflection from concave surfaces including a purely cylindrical concave reflector and a composite one consisting of a concave cylindrical arc transitioning to a straight inclined surface is the subject of the present study. A combined – theoretical, numerical and experimental – approach is used. The main attention is given to the transition from a Mach reflection to a regular reflection. New theoretical predictions of the transition are based on the information on the corner signal propagation obtained from numerical simulations via an original signal tracking technique. Numerical simulations are carried out using the Euler and Navier-Stokes models. State-of-the-art time-resolved optical flow visualization is employed in shock tube experiments. The obtained results and conclusions significantly alter the current state of knowledge about the phenomena.
