Numerical simulation of shock wave propagation n a mixture of a gas and solid particles

A numerical method based on the cubic interpolated polynomial (CIP) approach is applied for simulation of two-velocity two-temperature two-phase flow dynamics. Validation of the results is provided by numerical tests. A problem of shock wave propagation in a mixture of a viscous heat-conducting gas and solid particles of essential volume fractions is investigated as an application case. The influence of the particle size and drag coefficient formulation on the flow pattern, in particular, on the temperature behavior within the relaxation zone is revealed. A comparison with experimental dependences of the parameters behind the shock front on the Mach number is performed.
