Drift of elastic floating ice sheets by waves and current, part I: single sheet

The drift motion of a freely floating deformable ice sheet in shallow water subjected to incident nonlinear waves and uniform current is studied by use the Green–Naghdi theory for fluid thin plate an elastic sheet. wave- current-induced forces are obtained integrating hydrodynamic pressure around body. oscillations translational then determined substituting flow-induced into equation resulting governing equations, boundary matching conditions solved two dimensions with finite difference technique. surge motions analysed broad range body parameters various wave-current conditions. It demonstrated that wavelength length ratio plays important role response sheet, while mass rigidity have comparatively less impact. also observed presence ambient changes speed significantly (almost linearly), it has little no effect on its oscillations. However, under same current, remarkably wave period (or wavelength).
