A NOTE ON THE PROBLEM OF AN OSCILLATING SUPERCAVITATED HYDROFOIL NEAR A FREE SURFACE.
Abstract
The objective of the study was to determine the steady and unsteady forces and moments on a fully caviated hydrofoil operating near a free surface. The approach assumed linearized, two-dimensional, potential flow but no further limitations were placed on the values of Froude number, cavitation number, or depth-to-chord ratio. Full account was taken of the gravity waves on both the air-water and cavity interfaces generated by the motion of the foil-cavity system. The report discusses the approach to the general problem based on a representation of the system by distributions of elemental singularities. The solution for the steady motion of a deeply submerged, supercavitated, flatplate foil is obtained in this manner. (Author)
