摘要

对一种新设计的浮动双腔振荡水柱波能转换装置的效率进行了全面的实验研究。在Rezanejad和Guedes Soares之前的设计（2021年）的基础上，进行了大量的几何改进，以提高其水动力性能。研究了动力起飞阻尼和波浪特性对其水动力性能的影响。实验结果表明，与之前设计的浮动双腔振荡水柱装置相比，该装置在大范围海况下的水动力性能显著提高。具体来说，新系统在所有海况下的平均水动力性能为61%，比之前设计的效率提高了49%。此外，研究还强调，在特定的波周期范围内，该装置的前后腔在吸收波能方面起主导作用，它们之间的相互作用显著提高了整体的水动力性能。效率的大幅提高凸显了新设计的装置在波浪能转换应用方面的潜力。

Experimental study on the hydrodynamic performance of an innovative floating dual-chamber oscillating water column

A comprehensive experimental study investigates the efficiency of a newly devised concept of a Floating dual-chamber Oscillating Water Column Wave Energy Converter device. Built upon the previous design of Rezanejad and Guedes Soares (2021), substantial geometrical improvements have been made to enhance its hydrodynamic performance. The study examines the influence of Power Take-Off damping and wave characteristics on its hydrodynamic performance. The experimental results demonstrate a significant increase in hydrodynamic performance across a wide range of sea states compared to the previously designed floating dual-chamber Oscillating Water Column device. Specifically, the new system exhibits an average hydrodynamic performance of 61% in all sea states, representing a 49% improvement over the efficiency of the previous design. Additionally, the research highlights that the device's fore and rear chambers play a dominant role in absorbing wave energy within specific wave period ranges, with their mutual interactions significantly enhancing the overall hydrodynamic performance. This substantial improvement in efficiency underscores the potential of the newly devised device for wave energy conversion applications.
