Experimental Investigation and Simulation on Hydrodynamic and Mass Transfer Characteristics in Vibrated Three-phase Fluidized Bed

摘要

Computer fluid dynamics (CFD) method combined with experimental method was used to simulate and research the hydrodynamics of three-phase fluidized bed in this paper. The simulation result presented the distributing rule of pressure, velocity and local phase holdup in three-phase fluidized bed. A set of vibrated three-phase fluidized bed experimental system was designed and the hydrodynamics in vibrated three-phase fluidized bed were investigated In this paper, bed pressure drop, bed expansion rate and average liquid holdup were investigated systematically.
