Abstract:

The objective of this research is to develop a new powerful capability, which is called SNOW simulation of nonlinear ocean wave-field, for predicting the evolution of large-scale nonlinear wavefields using direct phase-resolved simulations. Unlike the phased-averaged approaches, SNOW models the key physical mechanisms such as nonlinear wave-wave, wave-current, wave-wind and wave-bottom interactions and wave breaking dissipation in a direct physics-based context. SNOW is now capable of simulating the nonlinear evolution of phase-resolved ocean wavefield in a domain of 100km x 100 km for a evolution time of Ohour.
