| Abstract: | The flows of nonlinear waves overtopping an obstruction are studied numerically in the present paper. The finite difference method is used to solve the full two dimensional Navier Stokes equations, and the VOF method is adopted to deal with free surface deformations. Numerical results of a solitary wave and periodic waves overtopping an rectangular cylinder are obtained respectively. Many complex phenomena, such as water accumulation, wave run up, water jet flows, water jet impact both upon free surface and on a structure, and generation of new waves on the lee side during the process of the waves overtopping an obstacle, can be successfully simulated. |
