A Nonlinear Calculation of 2-Dimensional Hydrofoill with Shallow Submergence

For treating a hydrofoil moving with nonzero angle of attack, first, Tulin's theory[1] is extended, and some computational results are given. Then a newly developed source-vortex panel code, which employs a nonlinear free surface boundary condition proposed by Lee[2] and satisfies the Kutta condition, is explained, and its results are compared with the existing experimental data and other numerical results. Overall performance of the developed code is shown as satisfactory.
