The upward turbulent gas-particle flow in a channel was studied usingan Eulerian-Eulerian two-phase model taking into account the feedbackfrom the particles on the gas-phase. The objective is to study theinfluence of particles with different diameters and volume fractionson the flow and particularly on the accumulation of particles in thenear wall region due to the turbophoretic effect. The results wereobtained with a two-phase flow model that is presented. Theaccumulation of particles in the near-wall region was found to bestrongest for particles with τp+ = 13. The model also shows thatvarying the particle diameters leads to different feedback of theparticles on the turbulent flow.
