This paper investigates the unsteady structures and the hydrodynamics of cavitating flows. Experimental results are presented for a Clark-Y hydrofoil fixed at α = 0°, 5° and 8°, for various cavitation numbers, from subcavitating flow to supercavitation. The high-speed video camera and the particle i...
