Shock wave reflections in dusty gas

Shock wave reflections in a dusty gas are studied by means of a vertical shock tube, where two cases are considered. In the first case the reflection of a dusty gas shock wave at the closed end of a shock tube is investigated and the effects of the relaxation phenomena on the pressure history and the shock wave propagation are shown. In the second case the pressure history of transmitted and reflected shock wave is measured in a sudden area constriction. In both cases the influence of Mach number and loading ratio is investigated. Numerical calculations are mainly made using the piecewise-linear-method which is applied to one- and two-dimensional shock wave proapgation in a dusty gas.
