论文摘要
该研究检查了倾斜的多孔床对面向倾斜水波的振荡水柱（OWC）设备效率的影响。靠近刚性壁的垂直，表面刺穿的薄板近似于OWC。使用线性电位理论的多域边界元素方法模拟系统。评估并讨论了不同的倾斜床结构参数以及入射波角度对OWC性能的影响的影响。该模型对保护近岸海洋设施的防波堤的重要性也得到了强调。发现OWC效率对多孔海床的斜率高度敏感，并且发现海床孔隙率可以稳定谐振频率，以防止水位变化。发现OWC比具有较高摩擦系数的多孔海床更有效。结果表明，该参数的最佳值是管理该波动能量转换系统的最佳值，可用于模型的设计和实现。
The study examines the influence of a sloping porous bed on the efficiency of an oscillating water column (OWC) device facing oblique water waves. A vertical, surface piercing, thin plate near a rigid wall approximates the OWC. The system is simulated using a multi-domain boundary element method assuming the linear potential theory. The impact of varying sloping bed structural parameters and influence of the incident wave angle on the performance of the OWC is evaluated and discussed. The significance of this model to act as a breakwater protecting near-shore marine facilities is also highlighted. The OWC efficiency is found to be highly sensitive to the slope of the porous seabed, and seabed porosity is found to stabilize the resonant frequency against changes in water levels. OWCs are found to be more efficient over porous seabeds with higher frictional coefficients. The results indicate optimum values for the parameters governing such a wave energy conversion system that can be used for the design and implementation of the model.
