The cavitation performance of a three-bladed inducer is studied in this paper. The inducer with different tip clearances was tested at different flow rates. Two pressure transducers are installed at inducer inlet to measure unsteady pressure to differentiate several types of cavitation instabilities. Only the synchronous rotating cavitation is found before the cavitation performance curve breaks down at all low tip clearance conditions, and the synchronous rotating cavitation is strengthened and starting cavitation number increases with higher flow rate. Experiment results indicate that the synchronous rotating cavitation could be suppressed by high tip clearance and almost completely vanished with the largest flow rate.
