Summary: The flow structure in the region of intersection of two stationary plane shock waves in a dusty gas is investigated. The regular symmetric and asymmetric shock interaction and the symmetric Mach interaction are considered. For a small particle mass concentration, on the basis of numerical calculations using the full Lagrangian approach it is shown that behind the shock wave intersection point a long thin region is formed, in which the particle trajectories intersect and the particle concentration sharply increases. A parametric study of the particle concentration distributions in this region is performed and the range of governing parameters on which the particle focusing effect is maximal is found.
