Numerical studies of transportation of granular material by a pin-point blast using models of the mechanics of continuous and granular media

Mathematical models for numerical studies of transportation of a mass of loose granular material during occurrence of a series of deep gas-dynamic ejections are developed using methods of the mechanics of continuous and granular media. Features of the kinematics and dynamics of development of this phenomenon are analyzed. Results of a numerical experiment and recommendations on use of the models in studies of specific transportation regimes are given.
