摘要：Fluidized bed systems have the potential to be widely utilized in the facility generation, mineral dressing and chemical industries. One factor limiting their increased use is the lack of adequate design techniques for the scaling such systems. An experimental setup of fluidized bed has been fabricated with an internal diameter of 50mm with an air as fluidizing medium, with sand as a bed material. Bed pressure drop was measured as a function of superficial velocity. For the same setup, a CFD model has been developed for simulating gas-solid fluidized bed. The model uses a multi-phase Eulerian-Eulerian technique to predict the transient behavior of fluidized bed systems. The commercial CFD code FLUENT 6.3 is used as the computational frame work for solving the discredited equations. The model is used to predict hydrodynamics in a three-dimensional fluidized bed. The minimum fluidization velocity and pressure drop was compared with experimental values and found to be in aggregate with CFD results. It can be concluded that CFD is a valuable tool in fluidized bed design.
