| Research Abstract |
In this study, a new numerical wave tank (NWT) model was proposed, which is combined a direct-forcing immersed boundary (IB) method to handling interface problems with complex geometry on a standard regular Cartesian grid and the volume of fluid (VOF) method to track the free water surface. The developed NWT model was applied in several case studies, including the wave force on a horizontal cylinder and dynamic behavior of tension-leg floating body. The methodology developed in this study serves as a good tool for solving many practical problems.
