Role of particle collisions in shock wave interaction with a dense spherical layer of a gas suspension

Аннотация

The problem of interaction of an expanding spherical shock wave with a layer of particles is considered within the framework of the model of mechanics of continuous media with due allowance for granular pressure in the dense gas suspension. The influence of particle collisions on the shock wave expansion process is analyzed. Generation of collisional pressure and formation of shock wave structures in the gas suspension are found to be the governing factors of motion of the cloud of particles at the initial stage.
