Abstract

The interaction between a solitary wave and a submerged semi-circular cylinder is investigated using a new potential-theory based, fully nonlinear two-dimensional numerical wave tank. The acceleration potential method is employed to calculate the hydrodynamic forces exerted on the cylinder. By using the present method, good time predictions in both the positive and negative horizontal force peaks are achieved. However, the current method gives poor predictions in force magnitudes, mainly because it is unable to take viscous effect into account when flow separation or vortex shedding happens. In addition, it is found that the weakly deformed solitary wave, compared with the undeformed wave, has a slight effect on the hydrostatic force exerted on the cylinder. The simulation result also reveals that the total vertical force exerted on the cylinder reach its peak when the solitary wave crest is right above the center of the submerged cylinder.
