This work provides a novel approach that combines computational fluid dynamics (CFD) with computational solid mechanics (CSM) to dynamically simulate the fully coupled hydroelastic interaction between nonlinear ocean waves and a submerged horizontal plate breakwater (SHPB). Based on a systematic series of simulations, it is shown that the wave damping performance of an SHPB can be evidently improved by an appropriate extent of deformation, which can be achieved through the design of its bending stiffness by varying elasticity and/or aspect ratio. The wave attenuation effect is found to be maximized when an SHPB has a deformation amplitude close to the incident wave amplitude. By accounting for the hydroelastic effect through the fully coupled CFD+CSM approach, this work presents a new computational technique that supports the design of deformable offshore and coastal structures.

采用全耦合水弹性方法设计淹没水平板防波堤

这项工作提供了一种将计算流体动力学 (CFD) 与计算固体力学 (CSM) 相结合的新方法，以动态模拟非线性海浪与淹没水平板防波堤 (SHPB) 之间的完全耦合的水弹性相互作用。基于一系列系统的模拟，表明SHPB的波浪阻尼性能可以通过适当的变形程度得到明显改善，这可以通过改变弹性和/或纵横比来设计其弯曲刚度来实现。发现当 SHPB 的变形幅度接近入射波幅度时，波衰减效应最大。通过完全耦合的 CFD+CSM 方法考虑水弹性效应，
