An experimental study on shock waves propagating through a dusty gas. The flow in a horizontal dusty-gas shock tube.

Abstract

An experimental study was conducted on shock waves propagating through a dusty gas in a horizontal channel using a horizontal dusty-gas shock tube. As dusty gas, air containing fly ash (mean diameters of 3 μm and 4μm) was used. Pressures and particle concentrations behind the shock waves were simultaniously measured by means of pressure transducers and a laser beam attenuation method. Variations of particle concentrations behind the frozen shock waves and the effect of particle loading ratios on the frozen shock wave Mach numbers are shown, and schlieren photographs of shock waves in a dusty gas taken with an Imacon 790 camera are shown.
