Rotating Drum Half-Filled With Large Beads in Liquid: Fictitous-Domain Simulation and Experiment

To numerically simulate “bedload transport” of sediment by a turbulent flow over an erodible bed, our group has been developing “fictitious domain” methods to handle dense-phase particulate flow in turbulent flow of liquid. We report on efforts to check our simulation method against experiment for a dense-phase particulate flow in liquid, namely a rotating drum half-filled with spherical particles. Overall agreement between experimental and simulated values of static and dynamic angle of repose is found to be quite satisfactory, both in air and in oil.
