| 摘 要： | 探讨了低雷诺数(Re)效应对涡轮压气机特性的影响,分析了随着海拔高度的增加压气机处于非自模区的流量界限,并通过相似模型理论推导了高原发动机涡轮增压的效率修正公式,利用这一结论能够快速地估算高原发动机性能,并为高空低Re对发动机性能的影响提供了理论依据。

| Abstract: | The influences of low Reynolds number on turbine compressor characteristics were researched,the boundary trend of compressor gas flow that worked in non-self-simulated domain with the increase of altitude was analyzed,and finally the correction formula of plateau turbocharging efficiency was deduced with the similarity theory.With the conclusion,the plateau performance of engine could be quickly estimated,which provided the theoretical reference for analyzing the influence of low Reynolds number on engine p... |
