1CFD simulation of fluidization quality in the three-dimensional fluidized bed显示文摘Multiphase computational fluid dynamics(CFD)has become an alternative method to experimental investigation for predicting the fluid dynamics in gas-solid fluidized beds.The model of Brandani and Zhang,which contains additional terms in both the gas-and solid-phase momentum equations,is employed to explore homogeneous fluidization of Geldart type A particles and bubbling fluidization of Geldart type B particles in three-dimensional gas-fluidized beds.In this model,only a correlation for drag force is necessary to close the governing equations.Two kinds of solids,i.e.,fine alumina powder(dp=60 lm and qp=1500 kg/m3)and sand(dp=610 lm and qp=2500 kg/m3),are numerically simulated in a rectangular duct of 0.2 m(long)0.2 m(wide)0.5 m(high)size.The results show good agreement with the classic theory of Geldart.Kai Zhang Stefano Brandani Jicheng.
