An experimental investigation was made to clarify the unsteady characteristics of the cavitation on an oscillating hydrofoil. The behavior of the cavitation affected by the hydrofoil oscillation is discussed based on the measurement of the pressure fluctuation upstream of the hydrofoil and the visual observations using the high-speed video recording. Concerning the response of the cavity to the pitching motion of hydrofoil, the amplitude of cavity length fluctuation and the phase difference between the angle of attack and the cavity oscillation were measured. In addition, the amplitude and the phase angle of the inlet pressure fluctuation were measured. And furthemore, the correlation between the pitching oscillation of hydrofoil and the self-oscillation of cavitation was investigated.
