Abstract

The reflection of shock waves over straight reflecting surfaces in steady flows was investigated experimentally using the hypersonic wind tunnel of Laboratoire d'Aerothermique du CNRS at Meudon in France. The results for M"SUB 0" =4.96 contradict the state of the art regarding the regular left and right arrows Mach reflection transition in steady flows. Not only was a hysteresis found to be existing in this transition, but also, unlike previous reports, regular reflection configurations were found to be stable in the dual-solution domain in which theoretically both regular and Mach reflection are possible.
