The present paper focuses on numerical simulation of wave processes observed in near-wall fluidized layer under action of normal shock wave. The unsteady process of interaction is described for various shock wave intensities and layer densities. It is shown that shock wave intensity increases significantly in the dense layer and the gain factor does not depend on the shock wave Mach number and defined only by the density ratio. Two different schemes regular and Mach of shock reflections are observed in computations that lead to a principally distinguished scenarios of instability development in a dusty layer.
