| 摘 要： | 级间导叶是多级离心泵的重要组成部件,对泵性能有重要影响。基于国内外研究提出了级间导叶的四种设计方法,分别为改进径向式导叶设计法、四条流线包围流道设计法、中间流线矩形扫描法和中间流线圆形扫描法。为某多级液氢泵分别设计一种径向式导叶和四种流道式导叶,验证了设计方法的可行性。对径向式导叶及四种流道式导叶进行了数值仿真研究,结...

| Abstract: | The interstage crossover is an important component in multi-stage centrifugal turbopumps. It has a significant effect on the performance of pump.On the basis of investigating overseas' advanced configurations,four possible design methods for the vaned cross-over configuration are proposed. The cross-over region for a multistage liquid hydrogen pump is designed with these methods whose correctness is validated.Every configuration is analyzed with CFD.The Centerline Circle Section Method is the best one for r... |
