Abstract
Centrifugal pumps need to be stopped in the case of closing valve sometimes due to some specific application requirements. This paper presents a
numerical simulation of the unsteady flow inside a low specific speed centrifugal pump during closed-valve forward and reverse stopping process.
The study results show that the average internal pressure gradually decreases during stopping periods. At the same blade radius, the pressure on
working surface is significantly higher than the suction surface. The pressure gradually increases from the impeller inlet to the outlet. The simulation
fully shows the transient flow characteristics inside the centrifugal pump during forward and reverse stopping period.
