| 摘要： | An analytical model for the horizontal multilayer porous plates has been developed based on linear potential theory. Energy dissipation across the horizontal porous plates is considered with an equivalent linearized porous boundary condition, and porosity-dependent drag coefficient estimated by CFD solutions. The hydrodynamic performance of the horizontal multilayer porous plates is assessed by estimating the reflection, transmission, energy loss coefficients, as well as wave force on each porous plate. The developed analytical model is verified by comparing with experimental and CFD-based numerical results. The parametric study with several key parameters such as porosity, submergence depth, number of plates, and their combination is performed in detail to search for the optimal design of the horizontal multilayer plates suitable for the development of eco-friendly wave barrier. It is concluded that a significant reduction in the wave transmission and high energy dissipation can be achieved by the dual-plate configuration with appropriate porosities and submergence depths, compared to the single-and triple-plate configurations. |
