5 Figure 3: Granular flow regimes and the Froude number associated with each bed movement [13] Yin et al. [14] stated that the flow into the active layer depends mainly on both the Froude number (Fr = ω2R/g, where ω is the angular velocity of rotation and g the acceleration of gravity) and size ratio ( O= ã/, where ã is the particle diameter and the …
