Abstract

Abstract

A time-domain send-order method is employed to study nonliear wave radiation around two-dimensional body.The free-surface boundary condition and the body boundary condition are satisfied to second-order at each time step, reflection waves are absorbed with artificial damping zone.The FEM with time marching is used to solve this problem.Oscillating of a horizonal semi-submerged circular cylinder is selected to confirm the validity of the calculation method.The time histories of wave elevations and hydrodynamics on the cylinder are calculated.Some results are compared with those obtained by previous theory and experiment, and a satisfactory agreement is obtained.
- Nonliear wave,
- second-order theory,
- artificial damping
