Abstract
The present work is devoted to the prediction of added resistance and the free heave and pitch motion response in regular waves. The numerical results are analyzed in terms of added resistance, ship motions. Both free to heave and pitch are studied to investigate the contribution to added resistance from ship motion at different wavelengths, and the results show that when the wavelength λ < 4Lpp the added resistance induced by ship motion is not negligible. The comparison with experimental results shows that unsteady RANS predicts the ship motion of heave and pitch well in all wavelengths. Ship pitch and heave motion in regular head waves can be estimated accurately by CFD.
