Prediction of particle velocity in a dilute turbulent gas-particle flow nearby a flat solid boundary is investigated numerically using a fully Eulerian two-fluid model. The particulate phase model is based on the kinetic theory of granular flow. The turbulence in both phases is modelled. Inter-particle and particle-wall inelastic collisions are considered. Effects of presence/absence of particulate phase turbulence modelling on velocity of particles are investigated. Results indicate that turbulence modelling is necessary for particulate phase, but conventional models should be modified to consider particulate flow nature. Effects of free stream velocity and particle diameter on turbulence modelling results have been discussed.
