An experimental study was performed on gas-particle supersonic unsteady flows past blunt bodies (an axisymmetric flat-faced cylinder and a two-dimensional circular cylinder) installed in a horizontal dusty-gas shock tube. For dusty gas air containing fly ash (mean diameter 3μm) was used. The experiment was carried out for frozen shock Mach number from 1.2 to 2.7 and initial loading ratio of the particles in the gas below η_o = 0.01. Schlieren photographs of the shock waves past blunt bodies taken with an Imacon 790 camera are shown, and the effect of suspended particles on the stagnation pressure histories of the blunt bodies are also shown.
