Experimental Observation of the Structure of Shock Waves in Dusty Gas,
Abstract
The structure of shock waves in dusty gas was studied by shock tube experiments. Pressure, shock wave velocity and dust concentration were measured under the condition that the dusty loading ratio was less than 0.4 and the shock Mach number was less than 1.5. The frozen and equilibrium pressures behind the shock wave can be well described by the Rankine Hugoniot relation. But the relaxation length was significantly shorter than that calculated from the drag of a sphere at steady motion. And the disperse shock waves in dusty gas were observed. It was found that the presence of dust decreases the pressure fluctuation in the flow. The propagation velocity of the shock wave agrees with the result of the model analysis on an effective gas.
