在这份报纸,在一台高度装载的压缩机的流动行为和拓扑学结构有或没有血浆串联空气动力学的使活动(泛美航空公司) 被调查。优化模式,全部的压力损失系数,插头流动角度和拓扑的分析被认为在角落分离上学习血浆流动控制的效果和机制。介绍的结果有或没有泛美航空公司包括边界层流动行为,分开的流动和性能参数上的泛美航空公司的三种类型的效果,拓扑学结构和单个点的序列。二根分离线,颠倒的流动和逆流在吸表面上存在。endwall 上的生气流动是为角落分离的一个重要元素。泛美航空公司能减少 underturning 并且象全部的压力损失一样翻,导致流动转弯和空气动力学的性能的改进的全面增加。泛美航空公司能改变拓扑学结构,单个点的序列和他们的相应分离线。类型 II 和 III 泛美航空公司在控制角落分离并且比打字提高空气动力学的表演是更有效的我。
In this paper, flow behavior and topology structure in a highly loaded compressor cascade with and without plasma aerodynamic actuation (PAA) are investigated. Streamline pattern, total pressure loss coefficient, outlet flow angle and topological analysis are considered to study the effect and mechanism of the plasma flow control on corner separation. Results presented include the boundary layer flow behavior, effects of three types of PAA on separated flows and performance parameters, topology structures and sequences of singular points with and without PAA. Two separation lines, reversed flow and backflow exist on the suction surface. The cross flow on the endwall is an important element for the comer separation. PAA can reduce the undertuming and overturning as well as the total pressure loss, leading to an overall increase of flow turning and enhancement of aerodynamic performance. PAA can change the topology structure, sequences of singular points and their corresponding separation lines. Types II and III PAA are much more efficient in controlling comer separation and enhancing aerodynamic performances than type I.
