Hybrid simulation for studying wind-wave interaction. In the simulation, the wind turbulence is simulated using large-eddy simulation, and the broadband sea-surface wave field is simulated using the high-order spectral method. The wind and wave fields are dynamically coupled during the simulation using a fractional-step two-way coupling scheme. More details about the numerical method can be found in Yang et al. (2011, J. Comput. Phys.) and Yang et al. (2013, J. Fluid Mech.).
