摘要：

搅拌槽内的流场是决定混合、传热及传质等操作的基础，对流场的研究具有十分重要的意义，计算流体动力学是研究流场的重要方法。本文回顾了搅拌数值模型的发展历程，阐述了三十年来各种搅拌流场数值模拟方法的特点及其应用情况，对比分析了各种湍流模型的优缺点，并展望了未来搅拌槽内单相湍流模型的发展方向。

Abstract:

The flow field in stirred tank has a significant effect on mixing，heat and mass transfer and other processes occuring in the stirred tank. Accordingly，investigation on the internal flow field of the stirred tank is of great importance，and computational fluid dynamics（CFD）is one of the most popular methods. In this paper，development of the dimensionality of numerical model of the stirred tank is firstly reviewed. Subsequently，the principle and their applications of nine different stirrer modeling methods in last three decades are presented. Finally，the characteristics of four turbulence models are compared. The future development of turbulence modeling of single-phase turbulent flow field in the stirred tank is discussed.
