中文摘要：
固液搅拌反应器是过程工业中常见的单元设备,该反应器内固液两相的湍流特性以及相间相互作用等因素使得相关的数值模拟变得较为复杂。本文介绍了近年来用于处理旋转桨叶的方法和模拟连续相及离散相的数学模型,总结了这些方法和模型在预测固液搅拌反应器特性（包括速度和湍流特性、固相浓度分布、临界悬浮转速、颗粒层高、几何参数优化和颗粒特性）方面的应用,并对不同的方法和模型进行了展望,重点介绍了采用颗粒解析模型的欧拉-拉格朗日法在研究颗粒悬浮机理方面的应用前景。
英文摘要：
Solid-liquid suspensions in stirred reactors are widely used in many processing industries. Numerical simulations of solid-liquid suspensions are usually confronted with complications and challenges due to the complex flow characteristics of these systems, such as two-phase turbulence and interphase interactions. This paper reviews methods of simulating the rotating impeller and models dealing with the continuous and discrete phases of solid-liq- uid suspensions, and summarizes their recent applications in simulating related flow phenomena including velocity and turbulence components, solid concentration, just-suspended speed, cloud height, optimization of geometrical parameters, and particle shape and type. Perspectives regarding different modeling approaches are presented, and the Eulerian-Lagrangian approach with resolved particles is emphasized in order to address the underlying suspen- sion mechanisms in stirred reactors
