Abstract
We numerically simulate “bedload transport” of noncohesive sediment by a turbulent liquid flow over an erodible bed using a “fictitious domain” simulation method that employs a fixed Cartesian grid. We report here on comparison with a challenging dense-phase particulate flow, namely a rotating drum partially-filled with spherical particles, through which oil flows to form a free-surface flow. Overall agreement between experimental and simulated values for bed and free-surface angles is found to be quite satisfactory..
