Abstract

Development of mesoscale non-uniformities of the dispersed phase in dusty-gas flows with kinematic singularities is considered. As examples, the following flows with dispersed admixture are studied: a flow near a stagnation point of two colliding viscous streams, gas-dispersed flow near a rigid wall, flows with localized vorticity, an unsteady flow in a neighborhood of a zero acceleration point.
