Abstract : The flow resulting from the passage of a shock wave through a dusty-air layer is studied analytically and numerically. For the cases treated here, a shock wave is always reflected at the first contact surface separating the pure gas from the dusty layer and a shock wave is transmitted into the dusty layer. The transmitted shock wave is stronger. The criteria for the reflected wave in terms of the properties of the air and dusty layer are obtained based on an idealized equilibrium-gas approximation. Working curves are presented showing the effects of the suspended particles on the resulting flow. Similarly, at the second contact front of the dusty layer, a rarefaction wave is reflected and the transmitted shock wave transmitted into the air is weakened by this nonlinear interaction. The rarefaction wave reflects at the first contact front as a compression wave and proceeds through the layer to refract at the second contact surface where it reflects as a rarefaction wave and a transmitted compression wave.
