UNSTEADY FORCE MEASUREMENTS ON SUPERVENTILATED HYDROFOILS IN HEAVING MOTION

Unsteady force measurements and flow observations are carried out on superventilated hydrofoils in heaving motion. The dynamic behavior of these ventilated flows is quite different than that expected for supercavitating flows; generally the unsteady measured forces are larger than predicted by free streamline theory. The gas flow rate required to support the cavity depends upon frequency and amplitude of oscillation. Unlike steady ventilated flows, the pressure within the cavity exhibits large unsteady fluctuations.
