Abstract
An experimental program was conducted to investigate the characteristics of a fully cavitating two-dimensional flat plate hydrofoil in the presence of a free surface. The submergence of the hydrofoil was varied from the planing condition at the free surface to a depth corresponding to 2.16 model chords. Near the surface the cavities formed by venting to the atmosphere, but at the deeper submergences, they had to be artificially formed by supplying them with air. The normal force, the moment about the leading edge, the center of pressure location, the cavity length, and the volumetric air flow rate into the cavity are presented as functions of angle of attack, cavitation number, Froude number, and proximity to the free surface.
Additional Information
The work to be described in this report was performed mainly by one of us (Dawson) as part of the requirements for an Aeronautical Engineer's degree at the California Institute of Technology (June, 1959). It is thought, however, that the information gained in this research would be of interest to other people engaged in hydrofoil research even at this late date.
