本文提出了一种计算分流叶片离心叶轮内部流场的理论方法，并研究了长短叶片间的相互干扰。在长、短叶片上分布旋涡，模拟其对流动的影响，系统研究了旋涡的分布和数量，发现短叶片对速度场和压力场有显著影响，能有效地阻止流动的分离和分离流的发展。
This paper presents a theoretical method for calculating inner flow field in centrifugal impeller with splitter blades and investigates the interactions between long blade and short blade. The vortices are distributed on the long and short blade to simulate the effects on flow.A systematical study of distribution and number of vortices is conducted.It is found that the short blade has significant influence on the field of velocity and pressure,and it can prevent effectively flow from separating and evolution of separate flow.
