Abstract: Severe vibrations induced by flow instabilities in the nuclear reactor coolant pump (RCP) are detrimental to the safe operation of the pump. Due to the particular spherical casing in the RCP, the internal flow structures ...

Abstract: The blade trailing edge profile is of crucial importance for the performance and pressure pulsations of centrifugal pumps. In the present study, numerical investigation is conducted to analyze the effect of the blade ...

Abstract: Rotor–stator interaction, a major source of high amplitude pressure pulsation and flowinduced vibration in the centrifugal pump, is detrimental to stable operation of pumps. In the present study, a slope volute is ...

Abstract: To accurately capture the behaviors of cavitation and reveal the unsteady cavitating flow mechanism, a condensate pump inducer is numerically analyzed in a separate numerical experiment with large eddy simulation (LES) at ...
