| Abstract: | A 3D time domain program based on time domain Green's function has been further developed to simulate the interaction between waves and ships with forward speed.The radiation and the diffraction problems of a Wigley-hull-form ship at different forward speed were discussed, and the hydrodynamic coefficients and wave forces were computed to verify the accuracy and reliability of the 3D time domain program.The numerical results agree well with the experimental and reference results. |
