碩士 / 國立成功大學 / 水利及海洋工程學系碩博士班 / 97 / In present study a 2-D numerical viscous wave model was developed and applied to represent propagation of a solitary wave over a seawall on a real sea bed including run-up or overtopping phenomena. The numerical model solved the unsteady, two dimensional Reynolds Average Navier-Stokes (RANS) equation and the turbulent model ( model) for simulating the realistic fluid. A hybrid particle level set method was incorporated to capture the complex free surface. An immersed boundary method was adapted to present the behavior of fluid flow in the vicinity of irregular solid boundary in the Cartesian coordinate system. The numerical results were demonstrated by a serious of numerical experiments, such as the Zalesak’s problem, cavity flow problem, and a uniform flow pass through a cylinder. Finally, the present wave model was conducted to simulate the surface evolution as a solitary wave attacked the seawall of Taidung, Fugang and Sanhe of Taidung Taiwan. Including wave shoaling, run-up, run-down and overtopping phenomena were observed in numerical results and the relationships between run-up height and incident wave heights, the distance from wave incident to a seawall etc. were discussed briefly.
