Sedimentation of inertial monodisperse suspensions of cubes and spheres
Arman Ahmadi, Anthony Wachs
Abstract
At a density ratio of 2, Galileo numbers of 70 and 160, and volume fractions in the range of 0.01 to 0.2, the pronounced angular velocities of cubes and the resulting orientation- and rotation-induced lift forces significantly promote transverse motions and the likelihood of escaping from clusters. Consequently, cube suspensions are found to be structurally more homogeneous than sphere suspensions, in addition to being more isotropic in terms of their momentum transfer properties.
