| Abstract: | Based on two phase flow model considering collision pressure and the constitutive equation of granular material has been obtained experimentally by authors,the numerical investigations on intractions of shock waves with air/granular interface are carried out by using AUSM + scheme.The calculated results are in good agreement with experimental measurements.Effects of the strength of shock waves and the material density of particles on flow fields are discussed. |
