| 摘 要： | 依据"非定常两代流型"理论,验证了二维叶栅在均匀进气条件下,施加激励对其性能所起的改善作用,尔后重点研究了进口具有总压的周向畸变时,施加激励对其气动性能的影响。计算结果表明,在有无进口畸变时,施加一定的激励都会改善流场结构,气动参数有积极变化,压升和效率增加,特别是在流量比较小时,变化尤为明显.对于进口畸变和施加激励影响压气机性能的内在原因,从流场结构的变化方面进行了初步分析。

| Abstract: | Based on the theory of"two generation of unsteady flow type",the function of improving 2D cascade's capability by bringing in prompting with a uniform inlet flow has be validated.With the same procedure,study of the effects on capability with a distorted inlet flow is the emphases of this dissertation. With either uniform inlet flow or distortion inlet flow,the results show that the flow field would be ameliorated by bring in prompting,therefore the aerodynamic parameter would vary to a better quantity,such as the total pressure improve and efficiency being increased even when there is a small flux. |
