ON THE GAS DYNAMICS OF THE GRANULAR BED

The laws governing the evolution of a shock wave moving along a granular bed are established. Using the methods of similarity theory, a criterion of shock wave stability is formulated, which includes the main characteristics of a granular bed. A generalization of this criterion to the case of a porous layer is proposed.
