Abstract

Oscillating water column (OWC) wave energy converters can be integrated in harbor protection structures, such as vertical, rubble mound and piled breakwaters. The interaction between the incident wave and the structure, in which the OWC device is integrated, is significantly different, since the structure of the vertical breakwater is impermeable, while that of the rubble mound breakwater is porous. The performance of the OWC device for the three configurations is analyzed for a range of wave periods from 6 to 12 s and a wave height of 1 m. The OWC device integrated into the vertical breakwater shows the best performance (maximum mean pneumatic power of 70 kW), and the mean pneumatic power is globally 3 % higher than that of the OWC device integrated into the rubble mound breakwater (maximum mean pneumatic power of 67.4 kW). The performance of the OWC device integrated into the piled breakwater shows a similar trend to the OWC device integrated into the vertical breakwater for wave periods lower than 9 s, but it has a significant loss of performance for higher wave periods.

与三种护港结构集成的振荡水柱波能转换器的性能研究

振荡水柱波能转换器可集成于垂直、碎石丘、堆垛式防波堤等港口防护结构中。竖向防波堤的结构是不透水的，而碎石丘式防波堤的结构是多孔的，因此在集成了OWC装置的情况下，入射波与结构之间的相互作用有很大的不同。在波浪周期为6 ~ 12 s、波高为1 m的条件下，分析了三种结构下OWC装置的性能。垂直防波堤集成的OWC装置性能最佳(最大平均气动功率为70 kW)，全球平均气动功率比碎石丘防波堤集成的OWC装置(最大平均气动功率为67.4 kW)高3%。在波浪周期小于9 s的情况下，堆式防波堤集成的OWC装置的性能与垂直防波堤集成的OWC装置的性能表现出相似的趋势，但在较高的波浪周期下，OWC装置的性能损失明显。

期刊介绍： Defect and Diffusion Forum (formerly Part A of ''''Diffusion and Defect Data'''') is designed for publication of up-to-date scientific research and applied aspects in the area of formation and dissemination of defects in solid materials, including the phenomena of diffusion. In addition to the traditional topic of mass diffusion, the journal is open to papers from the area of heat transfer in solids, liquids and gases, materials and substances. All papers are peer-reviewed and edited. Members of Editorial Boards and Associate Editors are invited to submit papers for publication in “Defect and Diffusion Forum” . Authors retain the right to publish an extended and significantly updated version in another periodical.
