By Pro/E, a simple model of impeller and 3-D models of the whole impeller is built.The impeller internal flow field of AY centrifugal pump with fluent is numerically simulated.The standard k-turbulence model and SIMPLY algorithm are chosen by GAMBIT, the preprocessor of Fluent, flow field of fluid are simulated by using commercial code Fluent.The speed of centrifugal pump′s impeller and the pressure are analyed , the speed field and pressure field in the entryway of centrif-ugal pump′s impeller are got.The study shows numerical simulation method can really reflect the complicated flow of blade in-terior and can provide theory basis for the design and improvement of blade machine, The methodcan be applied in engineer-ing practice .
