摘      要：The management of a cooling-water supply system in a nuclear reactor is performed by valve and reactor coolant pump(RCP)control,which regulates both the pressure and the discharge between certain ***,the RCP has a significant unsteady flow when operating at different *** unsteady pressure pulsation and radial force vector are difficult to calculate because these are affected by the transient properties of the unsteady *** study explores the use of a commercial Computational Fluid Dynamics(CFD)code to comprehensively estimate the unsteady flow of the *** full 3D-URANS equations were solved for different flow rates,and some optimised cases for the unsteady flow were *** results showed that the numerical predictions were validated with the experimental data of a model *** code was used to estimate the velocity streamlines,pressure pulsation and radial force vector in the steady and transient *** flow rates were not equal for the inner and outer passage in the double volute ***,the pulsation of the pressure and radial force was effectively reduced by optimising the staggered angleα.An optimal case was observed whenα=30°.
