... ABSTRACT Bow wave breaking is very obvious for ship advancing in open sea, where strong nonlinear phenomenon, such as violent free surface and air-entrainment, can be observed. It is quite challenging to accurate predict the ship bow wave breaking. In the present work, adaptive mesh refinement...

... Dynamics (CFD) has been extensively used in marine hydrodynamics. Compared with previous methods like potential flow theory, CFD is more suitable for simulating complex two-phase flows, where violent free surface and large-scale flow separation may coexist. In addition, more detailed flow field information...
