An Application of Topological Method to Analysing the Three-Dimensional Flow in Cascades (Ⅱ)—— Topological Analysis on the Vector Field Patterns of Skin-Frictions and Section Streamlines
【摘要】 文中应用拓扑分析的方法,分别绘制了在特定工况下压气机叶栅和透平叶栅的表面摩擦力线圈,以及弯管横截面和透平叶栅横截面的二次流场流线图.分析了叶栅三元粘性流场中的旋涡结构。
【Abstract】 With an application of topologial analysis, in this paper the skin-friction line patterns on compressor and turbine cassade surfaces are depicted and the streamline patterns of the secondary flow fields in the cross section of a curved pipe and a turbine cascade are drawn under given conditions. In addition the structures of vortices within three-dimensional viscous flow fields in cascades are analysed.
