Abstract
When a shock wave propagates along a horizontal wall on which a small solid particle rests, the particle is lifted by shock-induced flow behind the shock. In the present study, the fluid forces acting on the particle and the motion of the particle are evaluated by numerical simulation to investigate dynamical characteristics of the particle. The particle Reynolds number is 6 000, and the considered time period is from the time when the shock hits the particle to the time when the boundary layer thickness grows to the same order as the particle size. As a result, the particle was successfully lifted in the present simulation, where the lift force on the particle changes with the clearance between the particle and the wall. Furthermore, it was found that factors such as the boundary layer profile, the particle shape, and the boundary layer transition cause data scattering observed experiment.
