摘要：

Based on the N-S Equation and the non-structured mesh technology, the 3D steady incompressible turbulent flow within a centrifugal pump with inducer was simulated. The internal static pressure distribution, velocity distribution and the delivery head were obtained. Moreover, cavitation was also analyzed. The numerical results show that cavitation mainly happens at the outer edges of the entrance blades and the roots of the exit blades in the inducer, the hub entrance and the roots of part blades in the centrifugal wheel. It's found that cavitation is related with the assembly angle of the inducer and centrifugal wheel. The numerical results agree with the experimental data very well.
