Abstract

Computational Fluid Dynamics (CFD) is used to numerically simulate the viscous air-water flow around a thin rigid floating plate subjected to surface waves, with the aim to improve the understanding of dissipative mechanisms in drifting and non-drifting conditions. CFD model is validated by comparing the obtained results against previously published data of Nelli et al. (2017). It is shown that the energy of the waves is dissipated by the water flow over both upper and lower surfaces of the plate. The dissipation increases as a function of steepness of incoming waves. On the upper surface of the non-drifting plate, overwash contributes to dissipation of the energy of steep waves, while this ..
