Abstract

Wave propagation and attenuation due to elastic coating of the sea surface is considered. In the two-way coupling model for wave motion in a two-phase medium, "viscous fluid-elastic shirt," accounting for the interaction between those phases is considered within the frame of a boundary-layer-type approximation. An asymptotic linearized model, including the Navier-Stokes equations for a viscous incompressible fluid and the deformable plate motion equations for an elastic cover, is analyzed within a wide range of governing parameters. The dispersion relationship for different Reynolds numbers shows different oscillation regions. The structure of the fluid flow is studied in detail for the two asymptotic limiting cases of relatively high and low impact ranges of the elastic coating on the surface wave propagation and damping.
