摘要：

The paper presents the results of mathematical modeling of dense layer motion and unsteady heat transfer apparatus of powder technology. The physical features of the flow of a highly concentrated granular medium are analyzed. It is shown that the application of the Navier-Stokes equations and the use of partial slip conditions of the medium on the wall adequately describe the hydrodynamics and heat transfer of granular medium. This was verified by comparing numerical results with experimental data.
