BOW IMPACT AND DECK WETNESS: SIMULATIONS BASED ON NONLINEAR SLENDER BODY THEORY

A simplified formula for the fully nonlinear flow field around a ship moving through ocean waves at finite forward speed is achieved using the slender body theory. The computational scheme is based on the boundary integral method and several numerical techniques are employed to overcome difficulties on the boundary such as at the intersection of the hull and the free surface. For a frigate model, simulations of bow wave breaking are carried out and the onset of deck wetness shows good agreement with experiments.
