Popis:	Unsteady flows of a gas with solid particles in a system of two plane “rotor–stator” cascades are investigated. The carrier-gas flow is modeled using the Navier–Stokes equations (pseudo DNS approach) and, for comparison, the Reynolds equations (URANS approach) with the Menter SST k–ω model of turbulence. In both cases, the equations are solved using a second-order finite- volume method. In the absence of particle collisions, the admixture motion is modeled using a Lagrangian approach and the colliding particles are modeled by the Monte Carlo method. The feedback effect of the particles on the carrier gas flow is taken into account. The influence of different factors of random nature (particle distribution over sizes, particle scattering after collisions with the blades, particle–particle collisions) on the admixture flow pattern and particle concentration profiles at the outlet of the stator cascade is analyzed.
