Movement of Solid Particles on and off Bottom of an Unbaffled Vessel Agitated by Unsteadily Forward-Reverse Rotating Impeller

open access: yesJournal of Fluid Science and Technology, 2008
An unbaffled agitated vessel having an unsteadily rotating impeller was employed as an apparatus mixing liquid and solid particles with the density larger than that of liquid. For this type of vessel, the movement of solid particles on and off the vessel
