Two types of two-dimensional analyses using the singurality method were made to clarify the unsteady characteristics of the cavitation on an oscillating hydrofoil. By a linear analysis based on the assumption of infinitesimal disturbances, typical behaviors of cavitation due to the pitching motion of hydrofoil were made clear for the cases with both partial and super cavitations. By a time marching analysis which allows a large cavity length variation, the effect of the pitching motion of hydrofoil on the transitional cavity oscillation was well simulated. Both of the analyses were validated through the comparisons with the experiments described in the previous report.
