Computation of Motion and Added Wave Resistance With the Panel-Free Method

摘要

Computations have been performed to predict motions and added wave resistances for ships at forward speeds. The radiation and diffraction problems of a ship with forward speed are solved with the panel-free method in the frequency domain. In this paper, the effect of the m-terms and forward-speed/zero-speed Green functions (GFs) on the solutions are investigated using two Wigley hull ships. Computed motions, hydrodynamic coefficients, and added wave resistances were compared with the experimental data.
