ANALYTICAL PREDICTION OF WALL EFFECT ON FULLY CAVITATING LIFTING FOILS, USING NONLINEAR THEORY

A Fortran computer program, compatable with the CDC 6000 series, has been developed to evaluate the effect of a closed-jet tunnel-test section on the force coefficients of arbitrarily cambered, sharpnosed, fully cavitating, two-dimensional hydrofoil sections. The numerical solution to this problem has been obtained using the nonlinear theory developed by T.Y. Wu in 1969. The theory employs an open-wake model, to represent the cavity downstream of the foil section. Results of the program include predicted force coefficients, streamline shapes and pressure coefficient distributions. Some comparisons are made with the predictions of two other nonlinear theories available for the infinite-stream case only. (Author)
