Shock wave diffraction and reflection around a dusty square cavity

摘要

The diffraction and reflection of planar shock wave around a dusty square cavity is investigated nu- merically, which is embedded in the flat bottom surface of a two-dimensional channel, and the induced gas-particle two- phase flow. The wave patterns at different times are obtained for three different values of the particle diameter. The com- putational results show that the existence of particles affects appreciably the shock wave diffraction and cavity flow.
