Abstract

The bow wave depending on the bow shape can be determined by relatively simple geometric parameters due to little influence of the downstream wave. Accurate prediction of the bow wave is essential for ship resistance and motion responses. In this paper, the benchmark ship model, the Blunt modified Wigley, is used for all the simulations. The bow wave generated by the Blunt modified Wigley hull at a constant speed in incident waves is considered. The bow wave and the ship hydrodynamics are investigated by using Reynolds-averaged Navier-Stokes (RANS) method with Volume of Fluid (VOF) method to capture the free surface. In-house computational fluid dynamics solver, naoe-FOAM-SJTU, is applied to predict the hydrodynamics. The added resistance and motion responses of the Blunt modified Wigley in incident waves are studied to help understand the effect of the wave length on motion responses. The 1st harmonic amplitude and corresponding phase for heave and pitch motions are analyzed in detail. Furthermore, the wave patterns are visualized to discuss the evolution of the bow wave.
