The effects of inlet casing geometry configuration on unsteady cavitation were examined with a 3-bladed inducer. The inlet flow and cavitation pattern in two different casings were visualized using PIV (Particle Image Velocimetry) and high-speed video. It was found that the rotating cavitation was suppressed when the tip clearance at the inducer inlet was increased. The vortex cavitation in tip leakage flow and cavitation in back flow are thought to affect the appearance of the rotating cavitation as a result of the inlet casing geometry configuration.
