Fluid-Particulate Flow: Pellet Mixing

Videos of pellet submergence at various impeller speeds. The videos are named as follows: sfm_pelletdiameterinmm_pelletloadinginkg_impellerspeedinrpm.avi .

With an increase in impeller speed the pellets start submerging into the fluid. For a pellet loading of 1.5 kg and 16 mm diameter pellets with a height to diameter ratio of 1.4:1 the critical submergence speed was found to be about 180 rpm from physical modelling experiments and simulations.

Movie 1: sfm_16mm_1.5kg_53rpm.avi          DivX format, 8.0 Mb	Mixing of 1.5 kg of solid pellets in a tank containing a solvent. Impeller speed = 53 rpm.
Movie 2: sfm_16mm_1.5kg_150rpm.avi DivX format, 12.0 Mb	Mixing of 1.5 kg of solid pellets in a tank containing a solvent. Impeller speed = 150 rpm.
Movie 3: sfm_16mm_1.5kg_180rpm.avi DivX format, 12.0 Mb	Mixing of 1.5 kg of solid pellets in a tank containing a solvent. Impeller speed = 180 rpm.
Movie 4: sfm_16mm_1.5kg_200rpm.avi DivX format, 12.0 Mb	Mixing of 1.5 kg of solid pellets in a tank containing a solvent. Impeller speed = 200 rpm.
