摘　　要：综述了二维前后向台阶，T型结构以及轴对称纯体等典型几何结构的分离再附流动的实验研究．介绍了不同模型分离再附流场特性以及它们之间的异同．详细论述了流动各参数对流场的影响，并简要分析了分离再附流动中存在的问题和发展方向．Experimental investigations of separated-and-reattaching flow of several typical geometry configUrations have been reviewed, such as backward (or forthward) facing step, T-shape structure, axisymmetric bluff body, etc. Behaviors of separation flow field produced by. different models have been compared with each other, with respect to their intrinsic relation. The effect of flow parameters on the flow field were discussed, and some issues which should be solved and developed are presented.
