波浪能转换器（WECs）是用来提取波浪能的。然而，这种装置对于商业应用来说仍然是昂贵的。为了通过与防波堤共同分担建设成本来降低微气泡水防波堤的成本，提出了一种集成的圆柱形微气泡水防波堤系统，该系统在超长防波堤前设置一个圆柱形微气泡水阵，以提取波浪能量并衰减入射波。本文旨在对整体圆柱形wecs型防波堤系统进行性能优化。使用了计算流体动力学工具openfoam®和基于势流理论的求解器HAMS®。openfoam®为改进版的HAMS®提供粘度校正，以便准确有效地预测集成系统的性能。对集成系统进行了参数化优化研究，发现了一种新的额外圆弧结构设置，可以显著提高集成系统的性能。
Wave energy converters (WECs) are built to extract wave energy. However, this kind of device is still expensive for commercial utilization. To cut down the cost of WECs by sharing the construction cost with breakwaters, an integrated cylindrical WEC-type breakwater system that includes a cylindrical WEC array in front of a very long breakwater is proposed to extract wave energy and attenuate incident waves. This paper aims to optimize the performance of the integrated cylindrical WEC-type breakwater system. A computational fluid dynamics tool,openfoam®, and a potential flow theory-based solver, HAMS®, are utilized.openfoam®provides viscosity corrections to a modified version of HAMS®in order to accurately and efficiently predict the integrated system’s performance. Parametric studies are conducted to optimize the integrated system, and a novel setup with an extra arc structure is found to significantly improve the performance of the integrated system.
