碩士 / 國立成功大學 / 水利及海洋工程學系碩博士班 / 98 / The purpose of this study is to study wave splashing, running, shoaling and breaking on the slopping bed. An evolution equation for mild-slope equation (EEMSE) model and RANS (Reynolds Averaged Navier-Stokes) model are used to simulate the wave transformations on the sloping bed. The RANS equations are used to calculate the flow field around the structures for various incident wave conditions. The model is employed to simulate the flow kinematics and the turbulence effects in the RANS equations. The significant benefit of the present study over the traditional way of analyzing wave propagation problems is to apply the RANS model and the embedding method by taking account of the fully nonlinear, viscous and turbulent effects on the physical problem. Coupling the Mild-Slope Equation model and RANS model, the wave transformations problem can be easily simulated. We have compared the numerical results with existing experimental data and found a close agreement between computational and measured data. The present investigation describes flow field and turbulence breaking waves on a slopping bed. The predicted wave deformation, mean velocity field, and turbulence distribution under the breaking wave are presented and discussed. The wave model has been tested for the case of wave propagation in the Letzer coastal waters of Yilan.
