An electrical impedance probe is used to study the properties of partial attached cavitation. The method uses a series of electrodes mounted flush to the surface of a cavitating hydrofoil to obtain ti.me-dependent information about the presence of liquid or vapor in the region of interest. The impedance technique is used to measure the near-surface vapor-phase velocity and the shedding frequency of the cavity. The dependence of velocities upon cavity dimensions is discussed, and the measured frequencies are compared to current cavitation theory.
