An analysis of the motion of small particles in a supersonic shock layer is described. It is assumed the mass fraction of the particles is small. The governing differential equations associated with a continuum theory of the motion of air-particle suspensions are solved for the case of supersonic flow over wedges, right circular cones at zero angle of attack, and past spheres and cylinders. Both approximate analytical solutions valid for thin shock layers and exact numerical solutions are obtained for the particle-phase flow variables. Results useful in estimating the extent of cratering and erosion damage to high-speed vehicles flying in the atmosphere are displayed graphically and employed to illustrate interesting features of two-phase flows past conical and blunt bodies. The importance of nonnegligible particle-phase volume fractions and distributions of particle sizes within the mixture are also discussed.
