Experiments on Circular-Arc and Flat-Plate Hydrofoils

Abstract

An investigation in the High-Speed Water Tunnel of the two-dimensional hydrodynamic characteristics of sharp-edged hydrofoils is described. The lift, drag, and pitching moment were measured in cavitating and noncavitating flows for flat-plate and circular-arc profiles. The theory of Wu for the forces on sharp-edged profiles in full-cavity flow and the experimental results showed good agreement over a wide range of attack angles.
