Computational simulation of dynamic loading of porous powdery medium by compressed gas

The possibility of application of coarsene particles method for the computation of one-dimensional nonstationary flows of two-velocity two-temperature and two-pressure mixtures of gas and contacting solid particles is shown. In order to regularize the difference solutions the local pseudoviscosities are added as to gas pressure as to pressure of dispersed phase with the help of special differential operators. The results of computational experiment on the research of the dynamic of acceleration of particles of porous powdery layer under action of compressed gas are represented.
