This paper is devoted to the search for numerical calculation for the flow field of impeller in the centrifugal pump. It is aimed mainly at giving an effective means for introducing and applying the finite element method (FFM) to the computational flow field of pump, and providing a good basis for the inverse problem design, optimized design and CAD. From the calculating practice, it can be seen that the new numerical method in this paper is simple and practical.
