A GENERAL THEORY OF UNSTEADY LOADS ON CAVITATING HYDROFOILS

A general numerical approach using a doublet lattice-source representation for the prediction of unsteady loads on cavitating, general planform, finite aspect ratio hydrofoils is presented. Results for both super and partial cavitating foils of high aspect ratio are compared to the two-dimensional results of Woods and exhibit excellent agreement. Low aspect ratio results compare favorably with existing numerical approaches for supercavitating foils. Additional results for partially cavitating low aspect ratio foils are also presented.
