碩士 / 國立中興大學 / 土木工程學系所 / 99 / In this study, a numerical simulation was presented to investigate the variations of wave height and water level between a submerged breakwater and a vertical seawall. The study also investigated how different flow depths affected wave height, water level, and wave condition between a submerged breakwater and a vertical seawall. Application of Renormalized Group k-Ɛ turbulence model to simulate turbulent transmission of waves was used to solve the control equation of Reynolds Averaged Navier-Stokes Equation (RANS), selecting FLOW-3D fluid dynamics to calculate and analyze the simulation of the system. After comparison with Gracia et al.(2004) experiment and simulation results, this simulation showed nice accuracy. The numerical simulation results show that the clapotis wave system forms between the submerged breakwater and the vertical seawall due to reflected wave from the vertical seawall. When the incident wave and reflection wave meet at different depths of submerged breakwaters, the water collects in different ways, resulting in higher wave height when the distance between the submerged breakwater and the vertical seawall is 0.25 and 0.75 times the wave length. The spatial variation of water set-up behind submerged breakwater is similar to that of the wave height.
