Wave energy attenuation by drifting and non-drifting floating rigid plates

Computational Fluid Dynamics (CFD) is used to numerically simulate the viscous air-water flow around a thin rigid floating plate subjected surface waves, with aim improve understanding of dissipative mechanisms in drifting and non-drifting conditions. CFD model validated by comparing obtained results against previously published data Nelli et al. (2017). It shown that energy waves dissipated water over both upper lower surfaces plate. The dissipation increases as function steepness incoming waves. On plate, overwash contributes steep while this effect slightly smaller when moving freely. Simple equations are for estimating height fluxes, which found be fair agreement present simulations. due shear stresses under seen higher body longitudinal direction.
