Abstract

The erosion and cratering of solid particles to the surface of high-speed vehicles could significantly shorten the lifetime of the engine and damage the structures, yet the physics of the particle-laden high-speed flow is not clearly understood. In the present study, we employed a Direct simulation Monte Carlo approach to obtain a high-speed flow over a double-cone at a Mach number of about 15.8 and unit gas Reynolds numbers of 4.114 × 105m-1. A one-way coupled Lagrangian particle methodology was established based on the obtained flow field to examine the dynamics of solid particles in the shock-dominated, recirculating double-cone flow and assess the surface impact due to the existence of various sizes of particles. The results showed that the first cone suffered an intense particle impact over a broader range of particle sizes than the second cone.
