碩士 / 國立中興大學 / 土木工程學系所 / 103 / In this study, a numerical simulation was presented to investigate the variations of wave hight and water level between a submerged breakwater and a vertical seawall. The study also investigated how different spacing affected wave pressure on the vertical seawall. This study selecting FLOW-3D fluid dynamics to calculate and analyze the simulation of the system. Application of Renormalized Group k-εturbulence model to simulate turbulent transmission of waves was used to solve the control equation of Reynolds Averaged Navier-Stokes Equation (RANS). After comparison with Garcia et al.(2004) experiment and simulation results, this simulation showed nice accuracy in water surface variation and water molecule velocity. The results show that the clapoits wave system forms between the submerged breakwater and the vertical seawall due to reflected wave from vertical seawall. When the incident wave and reflected wave meet at different depths of submerged breakwater, clapoits wave peak position changes due to the different spacing. When the distance between the submerged breakwater and the vertical seawall is 0.5 and 0.625 times the wave length, due to the seawall is closer to the submerged breakwater and the water level is affected by the reflected waves so the water level that back to submerged breakwater will set-up.
