| Abstract: | Laboratory study results on the damping of gravity-capillary waves (GCWs) on water covered with oil slicks are presented. The nonmonotonic behavior (the presence of a local maximum) of the dependence of the damp coefficient on the slick thickness has been ascertained. The dispersion relation for GCWs in the presence of a viscoelastic slick of arbitrary thickness has been numerically calculated; this confirmed the presence of a damp coefficient maximum as a function of slick thickness. The parameters of oil slicks (interfacial elasticity and viscosity) have been estimated in a wide range of their thickness from a comparison of the calculation results with the data from laboratory measurements of wave parameters on water covered with an oil slick. |
