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: Intense pressure pulsation, resulted from the flow structure shedding from the blade trailing edge and its interaction with the volute tongue and the casing, is detrimental to the stable operation of centrifugal pumps. In ...
