| Abstract: | A submerged vortex lattice method for calculation of the flow around a 3-D hydrofoil is presented.The normal dipoles are posted on a second surface submerged under the wing surface and on a tail vortex surface.The control points are posted on the wing surface.The nonlinear free surface boundary condition is considered and the hydrodynamics forces of the hydrofoil near the free surface are calculated by the submerged vortex lattice method.The computational results show that the present method is correct and available.This method can be used for the hydrodynamic computation of the varied hydrofoils and stabilizing fins. |
