An experimental study on gravity waves through a floating viscoelastic cover
Abstract(#br)We report the results of a laboratory study conducted to investigate the dispersion relation and attenuation of surface waves under viscoelastic floating covers. The study uses oil-doped polydimethylsiloxane (PDMS) with different viscoelastic properties quantified in-situ using a rheometer. An additional test is made with a floating PVC film to estimate possible attenuation in the boundary layer under the cover. Within the frequency range tested, the wavelength deviates from open water case negligibly under the PVC film.
