英文摘要：

In order to enhance the basis understanding on heat transfer and improve the industry application of three-phase fluidized beds including the vapor（gas）-liquid-solid fluidized bed, the heat transfer mechanism models and heat transfer coefficient expressions were analyzed and compared. The distinct features, the formed reasons and open problems were described. The results show that the accuracy of the dimensionless correlation of heat transfer coefficient is the highest among the heat-transfer correlations and mechanism models; and the developments of model and heat-transfer correlation based on the understanding of the process mechanism, nonlinear investigation and numerical simulation with the CFD on the heat transfer in multi-phase flow are the future research areas.
