Abstract

In the present paper, the development of a model scale Wave Energy Converter (WEC) and an experimental WEC test rig are presented, and results of numerical simulations and experimental measurements are shown. The presented point absorber WEC is coupled to a generic power take-off (PTO) and is restricted to pure heave motion in regular waves. Experiments were carried out at the Universidad Austral de Chile (UACh) Wave Tank and results from responses and efficiencies were compared with data from the BEM (boundary element method) code WAMIT. Numerical and experimental results showed good agreement. Finally, results were extrapolated and superposed with typical wave energy spectra found in different Chilean regions, providing a first performance estimation for a wave energy converter in Chile. Results are discussed and compared with an existing technology and give an insight of the potential for wave energy technologies in Chile. Further investigation is proposed for an analysis in irregular waves and the use of a more advanced PTO (power take-off) in the future.

升沉波能量转换器的水动力分析

本文介绍了模型尺度波浪能转换器(WEC)的研制和实验试验装置的研制，并给出了数值模拟和实验测量结果。所提出的点吸收器WEC与一般的动力起飞(PTO)耦合，并且仅限于规则波中的纯升沉运动。在智利南方大学(UACh)波浪槽中进行了实验，并将响应和效率的结果与边界元法(BEM)代码WAMIT的数据进行了比较。数值与实验结果吻合较好。最后，将结果与智利不同地区的典型波能谱进行外推和叠加，为智利的波能转换器提供了第一次性能估计。结果进行了讨论，并与现有技术进行了比较，并对智利波浪能技术的潜力进行了深入了解。提出了进一步的研究，以分析在不规则波和使用更先进的PTO(功率输出)在未来。
