Design and Simulation of Aeroengine Three Stage Combination Vortex Pump

摘要：

To solve the problem that single stage booster pump has the problem of low oil pressure at low speed conditioa This paper gave a design method for three stage combination vortex pump which uses radial series. In this method, the preliminary structural parameters of the vortex pump were designed by using the empirical coefficient method. Then Hex/Wedge grid is used to generate mesh for the established 3D model of the vortex pump. The final structure parameters were obtained by CFD numerical simulation optimization iterately. Finally, the flow field of combination vortex pump was analyzed. Simulation results show that: The three stage combination vortex pump meet the design requirements.
