摘　　要：对控制环量方法在离心叶轮准三元设计中的应用展开了研究。根据给定设计点参数,通过该方法设计出了一背掠式离心叶轮,并对设计结果进行了分析。鉴于环量分布的重要性,讨论了不同类型分布对叶轮性能的影响,得出后加载型分布适合离心叶轮的结论。This paper focuses on the application of method of controlled circulation in the quasi three dimensional design process of centrifugal impeller. A back - swept impeller is designed upon the parameters of design point employing this kind of method. For the significance of circulation distribution, different types of circulation distribution and corresponding flow fields are presented. It comes to the conclusion that the later -loading type gives better performance for centrifugal impeller.
