Abstract: Cavitating flow in the impeller of a single-stage radial-flow pump at optimal flow rate and different values of NPSH (Net Positive Suction Head) is analyzed numerically using the VOF model of CFX-TASCflow. The size and the shape of the cavitation regions near NPSH3 agree well with the cavitation visualization inside the impeller at similar flow conditions.
