Abstract

Nonlinear interaction of surface and internal waves with very large floating or submerged structures T. Kakinuma Marine Environment and Engineering Department, Port and Airport Research Institute, Japan Abstract This paper describes interaction of surfacelinternal water waves with floatinglsubmerged platforms by considering nonlinearity of fluid motion and flexibility of oscillating structures. The model represents a multilayer fluid system interacting with horizontally very large and elastic thin-plates, where the set of governing equations is derived by vertical integration in each fluid layer with nonlinear boundary conditions satisfied on the interfaces. Numerical computation is performed for surfacelinternal long waves and floatinglsubmerged plate oscillations in the vertical section. Resonated pressures beneath a floating plate on the sea surface in a two-layer system are obtained in forced oscillation cases by taking into account different order of wave height to water depth ratios.
