| 摘 要： | 基于Aungier的环形扩压器性能分析模型,发展了大涵道比高低压涡轮间过渡流道的一维性能分析方法,并与等角直壁环形扩压器的试验数据进行了比较和验证。在此基础上,应用所发展方法以某涡轮过渡流道为算例,对模型进行了参数化研究,分别分析了涡轮过渡流道中线形式、进口Ma、进口堵塞和进口预旋等因素对涡轮过渡流道压力恢复、损失以及堵塞发展等的影响规律,得出了具有实际指导意义的结论。

| Abstract: | Based on the model developed by Aungier for exhaust diffusers, A one dimensional analysis method is developed for intermediate turbine duct (ITD), and the method is validated against available experiment data for equiangle rectilinear annular diffusers. Besides a parametric investigation is conducted for present method, factors, such as meanline determination, inlet Mach number, inlet blockage and inlet pre-swirl, are analyzed, and their influences on the ITD performance are established, which are useful for engineering application. |
