Turbulent gas-particle flows in the duct with fluid injection are simulated using large-eddy simulation technique. The numerical calculations are performed by the Eulerian-Lagrangian approach for the fluid and solid phases respectively. The model developed of motion of particles takes into account fluctuations of fluid velocity. The influence of inflow conditions, and the size and place of injection of particles on their dispersion pattern are investigated. The results obtained have a good agreement with the results computed on the base of Reynolds averaged Navier-Stokes equations and experimental data.
