To explore the influence of tip clearance on pressure fluctuation in a low specific speed mixed-flow pump, tip clearances delta of 0.25 mm, 0.75 mm and 1.00 mm, along with no tip clearance, were selected. The reliability of the simulation was verified by comparison with the experimental data of exte...
