Resum
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...
