| Abstract: | Flow field structure of unsteady cavitation flow around a Clark-Y type hydrofoil was experimentally investigated.Experiments were carried out in a rectangular test section of a cavitation tunnel.A high-speed video camera was used to visualize the unsteady cloud cavitation flow pattern,and a particle image velocimetry(PIV) was also used to measure instantaneous velocity field and vortex field in cavitation flow field around the hydrofoil.Experimental results show that cavitation phenomennon has an important ... |
