Development of a numerical wave tank based on IB method for the simulation of interactions between moving objects and waves

提出了一种新的数值波浪水槽模型，该模型结合了直接强迫浸没边界（IB）方法和流体体积（VOF）方法，前者用于在标准规则笛卡尔网格上处理复杂界面问题，后者用于跟踪自由水面。将所建立的NWT模型应用于多个算例，包括作用于水平圆柱的波浪力和张力腿浮体的动力特性。在这项研究中开发的方法作为一个很好的工具，解决许多实际问题。

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.
