Abstract：Three-dimensional numerical simulations of the internal flow field, based on Reynolds-average equations and RNG k-ε turbulence model, are carried out in the study on axial and circumfe-rential positions between guide vane and casing volute of a ns=390 mixed-flow nuclear reactor coolant pump. Energy performance is used to analyze internal flow and acquire the prime position between guide vane and casing volute. The result shows that different positions have an influence on hydraulic efficiency and internal flow. Hydraulic efficiency in an ideal position scheme has increased by 0.6%, equal to 1/4 of guide vane outlet width, between the shroud and central plane of casing outlet. Meanwhile, it has increased by 0.8% with a better internal flow performance as the symmetric axial plane and the vane outlet are at the same circumferential position. Results contribute to the design and optimization of a nuclear pump as well as internal flow control.
