Research on New Strucural Aero Fuel Centrifugal Pump Design

Article Preview

Abstract:

A inducer and impeller combination aero fuel centrifugal pump design method was given. Based on empirical coefficient method the preliminary structural parameters of the combination Centrifugal pump were designed firstly. Then the Centrifugal pump Hybrid Grid model was built with muti-block structure and octree style.The final structure parameters were obtained by CFD numerical simulation optimization. Finally, the flow field of combination Centrifugal pump was analyzed and compared simulation datas with test datas by making the test samples.The relative error of the design point doesn’t exceed 5%, indicates that the inducer and impeller combination pump meet the design requirements.
