【摘要】 目前振荡水柱式波能装置研究广泛，在复杂的远海波浪情况中，离岸式振荡水柱装置长期经受波浪作用，提高振荡水柱装置的生存能力已成为了研究热点。本文提出一种新型的集成透空结构的振荡水柱装置模型，基于线性势流理论和特征函数匹配法建立并求解数学模型，在验证了模型的准确性后，分别研究了透空结构的开孔率、布置距离的改变对集成系统水动力性能的影响；将设计的模型与单独的振荡水柱装置进行对比。研究发现：在消浪方面具有明显的优势，虽然其俘获能量的频带宽度有一定减小，但有效降低了振荡水柱装置受力和系统的透射系数。更多还原

【Abstract】 Many studies have been conducted on the abundance of wave energy, among which the oscillating water column(OWC) wave energy device has been widely applied. In addition, because wave conditions in offshore seas are complex, offshore OWC devices are subjected to wave action for long periods. Thus, improving the survivability of OWC devices has become a hot topic. In this study, a new OWC device model integrated with a permeable structure was proposed. Based on the linear potential flow theory and the eigenfunction matching method, a mathematical model was established and solved. After verifying the accuracy of the numerical model, the influence of the porosity and layout distance of the permeable structure on the hydrodynamic performance of the integrated device was studied. Thereafter, the designed model was compared with the single OWC device, finding that the integrated device had obvious advantages in wave dissipation. Although the frequency bandwidth of the captured energy was reduced to a certain extent, the horizontal force of the OWC device and the transmission coefficient of the system were effectively reduced.更多还原
