HYDRODYNAMIC FORCES INDUCED BY A SOLITARY WAVE ON A SUBMERGED CIRCULAR CYLINDER

A numerical two dimensional wave basin has been developed in the framework of potential theory of nonlinear free-surface flows. This general purpose computer code was used in this study to investigate systematically the interaction between a solitary wave and a fixed submerged circular cylinder. For a given submergence, different flow evolutions were encountered; their features are shown to depend on soliton amplitude and cylinder diameter. A quantitative study of hydrodynamic forces during the interaction is also presented.
