Abstract:The granular flow models on the basis of the kinetic theory are presented for numerical study on a dense particles bed with shock interaction. For the solid phase, the constitude equations are deduced from the interactions between the mean and the fluctuating motions of solid particles,the latter are represented as functions of the granular flow temperature. Numerical simulation by the AUSM+ schemes is employed to analyse the flowfield of the shock-induced fluidization of inert powder layers. It shows that the granular flow models are feasible to describle the flow with high speed and strong discontinunity.
