Abstrakt:	Experimental investigations and numerical simulations have been performed to study the transition between steady regular and Mach reflections induced by flow Mach number variation. The experiments have been carried out in the supersonic wind tunnel SIGMA 4B, at the Institut Aerotechnique (IAT) in St Cyr L'Ecole, France. Symmetric and asymmetric arrangements of wedges have been tested. No significant hysteresis phenomenon has been detected experimentally. However, this phenomenon has been revealed by numerical computations obtained by solving the Navier-Stokes equations. [ABSTRACT FROM AUTHOR]
