升力设计法是设计轴流式叶轮应用的很普遍的一个方法。这方法是通过逐次逼近的过程,使叶轮获得设计所要求的动力性能的,因此讨论升力法的收敛性具有重要理论
Lift design is a very popular method of designing axial flow impellers. This method is through successive approximation process, the impeller to obtain the required dynamic performance of the design, so the convergence of the lift method has important theory
