Abstract
Particle transportation in a fully developed turbulent duct flow is numerically investigated under the effect of wall-normal gravity force. The hydrodynamic modeling of the fluid phase is based on direct numerical simulation. The kinematics and trajectory of the particles as well as the particle-particle interaction are described by the discrete element method (DEM). By using a soft-sphere DEM where the particles and the walls are specified by material properties in the simulation, the effect of collisions on the particle resuspension rate is discussed. The collisions are found to influence on the particle resuspension rate near the duct floor whereas hardly affect the particle behavior near the duct center.
