概要

A surface panel method to analyze the hydrodynamic property of hydrofoil, strut and pod configuration in uniform flow is described. Free surface effect is taken into account by the negative images of the bodies. The model experiment of a hydrofoil system was performed in the towing tank and the cavitation tunnel at Nagasaki Experimental Tank, and compared with the calculation by the present panel method. The calculated pressure distribution and lift coefficient are in good agreement with the experimental data. It is found that the negative minimum pressure coefficient-C_<pmin>, calculated by the present panel method corresponds well with the cavitation inception index σ_i. From a practical point of view, the present method is one of the useful design tool for the hydrofoil craft.
