Abstract

A two-dimensional, fully nonlinear numerical wave tank (NWT) is established to study wave interactions with a submerged circular cylinder undergoing large-amplitude heave motions. The mixed Eulerian-Lagrangian approach is applied for the time stepping of free surface. The boundary value problems formulated for both the velocity potential and the acceleration potential are solved using the desingularized boundary integral equation method. The present NWT is verified by the analytical solution from Wu (1993) and the numerical results from Guerber et al. (2012). The free-surface nonlinearity is confirmed to be important when the cylinder is oscillating near the free surface. The effect of the submergence on the hydrodynamic force acting on the cylinder is also investigated.
