The paper presents numerical computations of particle-laden turbulent channel flow. The large eddy simulation (LES) approach for fluid and the Lagrangian particle tracking for the dispersed phase are applied. The continuous phase results for fully-developed channel flow at Re = 150 are in reasonable agreement with available reference data. In particular, the computed mean velocity profile and turbulence statistics are shown. The computed flow field is used to study the statistical properties of the motion of fluid and solid particles. First, trajectories of a set of marked fluid elements are computed to check whether their uniform concentration is preserved. Then, heavy particles are tracked in the flow. Particle interactions with the channel walls are assumed to be fully elastic and the effect of their inertia on particle number density profiles and on velocity statistics is assessed.
