一元流方法是径流式叶轮设计的基础.本文论述用一元流方法设计径流式叶轮高次和二次圆柱抛物面叶型的单弯形径向叶片及用于近代涡轮叶轮的二次圆柱抛物面叶型的双弯形径向叶片的设计方法和步骤,讨论压气机叶轮进口扩张角的计算方法及进口扩张角较小的径向偏斜式叶轮的设计方法;提出了用一元流方法.计算弯曲叶片槽道截面积的计算方法及叶轮子午面流道型线的快速逼近作图法.
The monolithic flow method is the basis of the design of radial flow impellers.This paper discusses the design of the single curved radial blades of the high-order and the secondary cylindrical paraboloid-type blades of the radial flow impeller and the double cylindrical paraboloid-type blades The design method and procedure of the double curved radial blade are introduced. The calculation method of the inlet divergence angle of the compressor impeller and the design method of the radial deflected impeller with small inlet expansion angle are discussed. Channel cross-sectional area of the calculation method and the impeller meridian flow line rapid approximation mapping method.
