Supersonic Flow of a Lightly Dust-Laden Gas past a Wedge

Abstract

The flow field behind an attached shock wave produced by a wedge fixed in a uniform stream of a gas containing small dust particles is examined theoretically by a perturbation method. The shock wave causes a deviation from an equilibrium state and bends downstream as a result of interaction with Mach waves. Far downstream an entropy layer is formed near the surface of the wedge, across which the pressure is constant but other flow variables change appreciably. Numerical values of the temperature and the pressure of the gas are given for a few cases showing that these variables take then maximum in the relaxation region next to the shock wave.
