摘要：The hydrodynamic problem of a two-dimensional wedge entering into a nonlinear wave in three degrees of freedom is investigated based on the incompressible velocity potential theory.The problem is solved through the boundary element method in the time domain.To avoid numerical difficulties due to an extremely small contact area at the initial stage,a stretched coordinate system is used based on the ratio of the Cartesian system in the physical space to the distance travelled by the wedge in the vertical direction.The mutual dependence of body motion and wave loading is decoupled by using the auxiliary function method.Detailed results about body accelerations,velocities and displacements at different Froude numbers or different waves are provided,and the mutual effect between body motion and wave loading is analysed in depth.
