Abstract
Large-eddy simulations of interactions between shock waves and particle clouds show that lower particle Reynolds numbers result in stronger shock wave attenuation and a stronger reflected shock wave. Velocity fluctuations are found to be most intense at moderate Reynolds numbers, while particle forces vary most at the highest Reynolds numbers.
