Description
Summary:In this paper has been carried numerical simulation of the interaction of the ion acoustic shocks and one-dimensional dust layers in the argon plasma. Plasmas studied in the frame hydrodynamics model, the charge of dust particles is determined according to the orbit-limited model, the potential of the self-consistent electric field is described by Poisson equation. As a result simulation the spatial distributions of plasma parameters are obtained at different times. It is shown that the velocity of dust ion acoustic shocks is increased at the front boundary, and one is decreased at the back boundary of the dust cloud.
