TL;DR: In this paper, the particle image velocimetry (PIV) measuring technique was used to measure the complex flow structures in a low specific speed centrifugal pump, and three typical interacting modes were observed at different flow rates, and the cutting effect of the volute tongue on the vorticity sheet is dependent strongly on the local absolute velocity distribution.
