摘　　要：固液悬浮是典型的单元操作,对其进行研究具有重要意义。回顾了60年来搅拌容器内固液悬浮的研究历程,介绍了常见的搅拌悬浮设备结构,对比分析了有挡板和无挡板时的临界悬浮转速,阐述了固液悬浮的各种实验测试及数值模拟方法,论述了自由液面变形对搅拌固液悬浮的影响及研究现状,并展望了未来在数值研究方面的发展方向。Solid-liquid suspension is one of the typical unit operations in the process industry and accordingly, study on the suspension performance is of great importance. In this paper, developments of investigations on the solid-liquid suspension in stirred vessels in the past six decades were reviewed. Subsequently, configurations of the commonly used stirred systems were introduced. The critical suspension speeds of solid particles in baffled and unbaffled stirred vessels were clarified and compared. Finally, the principles of different experimental and numerical methods related with solid-liquid suspensions were presented. Investigations on the effect of free surface deformation on solids suspension and the research status were briefly summarized. The future development of numerical simulation on the solid-liquid suspension in stirred vessels is discussed.
