Abstract A three-dimensional numerical investigation was carried out in a reactor coolant pump scale model at three different guide vane axial positions to study the influence of guide vane axial position on internal energy conversion characteristics of impeller, guide vane and pump casing by comparing and analyzing external characteristics, pressure field and velocity field,and based on Reynolds-averaged N-S equations and RNG k-ε turbulent model with multiple reference frame and SIMPLE algorithm. The results show that reducing the distance between the guide vane and the pump outlet pipe axis in the impeller rotation axis direction has great influence on the flow state and hydraulic loss of pump and flow components. Under the part-load conditions reducing that distance makes the efficiency of pump and impeller increase, which improves the flow state and suppresses the backflow phenomenon thus reducing loss of pump casing, but at the same time increasing the loss of guide vane. Under design and over-load conditions reducing that distance makes the efficiency of pump and impeller decrease, but the losses of guide vane and pump casing increase. Because reactor coolant pump′s parameters of the impeller, guide vane and the pump casing are related and influenced, changing the guide vane axial position will influence the coupling-matching characteristics between elements, and then influence the flow state and the energy conversion efficiency of the impeller, guide vane and the pump casing.
