| Abstract: | The problem of flow separation is important in modern fluid mechanics because of its theoretical values and practical applications. This paper mainly reviews three dimensional separated flow structure and its fundamental behaviour in the physical aspects. Following problems are discussed in detail; two types of flow separation modes and separation criterion for 3D steady flows; qualitative analysis of 3D separated flow with topology theory; the classification of 3D separated flows according to physical characteristics) the physical behaviour of separated surface. Finally recent studies of turbulent boundary layer separation are also briefly reviewed. |
