英文摘要：
The research progress of numerical and simulation of multiphase turbulent flow in a stirred tank, which was a common unit operation equipment in process engineering, was reviewed. The important mathematical and numerical aspects of computational simulation, such as turbulence model for multiphase flows, formulation model for inter-phase momentum exchange and treatment method of the impeller interaction, were discussed with brief comments and comparative analysis based on reports in literatures. Aimed at various multiphase systems in stirred tanks, numerical simulations of the impeller region, the interphase momentum exchange and the influence of introduced dispersed phases on the characteristics of turbulence were analyzed and compared. A few suggestions were presented for further in-depth research topics.
