- Abstract
- In this study, propeller cavitation and the resulting noise were analyzed experimentally in uniform inflow conditions. The propeller cavitation observation and noise measurements tests were conducted in the KRISO Large Cavitation Tunnel (LCT), with size 2.8m (B) × 1.8m (H) × 12.5m (L). The test setup and conditions are introduced and the propeller noise test procedure is briefly described. To investigate the propeller cavitation and induced noise, propeller noise measurement tests were performed under various pressure and propeller loading conditions. Propeller noise results are presented along with the cavitation observation. The relation between the cavitation patterns and measured noise were analyzed.
