Design and numerical simulation on guide vane of AP1000 Reactor coolant pump

Accorded to the way used in design radial diffuser of centrifugal pump, tree different guide vanes of AP1000 nuclear coolant pump were designed. Base on ANSYS-CFX the numerical investigation of internal flow in three different guide vanes was made, which gave the distribution of velocity and static pressure. Through 8 different flow conditions, performance curves of 3 different guide vanes and impeller were obtained. The results can provide some references to the design of guide vane of AP1000 Reactor coolant pump.
