Abstract:A comprehensive understanding of the flow regime transition is a prerequisite for designing and operating the rotating drum, especially when dealing with non-spherical particles. In this study, the multi-sphere method was used to construct cylindrical particles. The optimal number of spherical elements for particles with different aspect ratios was determined in terms of kinetic energy, rotational kinetic energy, collision number, collision force, deformation and angle of repose. And the effects of filling rat… Show more
