FREE-SURFACE EFFECTS ON THE APPARENT-MASS, QUASI-STEADY, AND WAKE CONTRIBUTIONS TO HYDROFOIL LOADS.

Abstract

The report presents the results of a theoretical study to determine the separate effects of a free surface on the quasi-steady, apparent-mass, and wake contributions to the hydrodynamic forces on an oscillating hydrofoil. A fully wetted foil in a two-dimensional, linearized, potential flow is considered with no limitations placed on the values of Froude number or depth-to-chord ratio. The solution takes full account of the surface waves caused by hydrofoil motion. Results are presented in tabular form. (Author)
