Flow and mixing of elongated particles in rotating drums of different sizes
Published 2025-07-01“…For both monodisperse and binary particle systems, dynamic angle of repose is determined mainly by a Froude number Fr, measuring the ratio of centrifugal force to gravitational force on a particle, while it is insensitive to scale-up ratio α, defined as the ratio of cross-sectional areas of the current drum to the reference one. Average particle velocity and contact force generally increase with both Froude number and scale-up ratio. …”
