将波能装置与防波堤等海洋结构物相结合,将有助于提升其经济性,促进其应用。以一定间距平行排布多个圆筒振荡水柱装置（OWC）形成波能利用型圆筒透空堤,并基于二维波浪水槽物理模型实验对其水动力特性展开研究,重点关注筒间距、OWC吃水、波高对于波浪防护和波能转换的影响规律。结果表明：圆筒较为紧密排布时,高效波能转换的波频范围显著拓宽;较浅OWC吃水在获得近似波浪防护效果的同时波能转换性能更佳;波浪防护效果及波能转换性能受波高影响较小。波能利用型圆筒透空堤在实际应用时,应采用较小的筒间距和OWC吃水,以同时兼顾较好的波浪防护效果和波能转换性能。
Abstract
Combining wave energy devices with marine structures such as breakwaters will help improve their economics and facilitate their application. Arranging a number of cylindrical oscillating water column devices （OWC） in parallel at a certain distance can function as wave-energy-utilization type cylindrical open breakwaters. The hydrodynamic characteristics are experimentally investigated based on a two-dimensional physical wave flume. The study focuses on the influences of cylindrical oscillating water column distance, OWC drafts, and incident wave heights on both wave protection and wave energy conversion. The results show that the wave frequency range of high conversion efficiency is significantly broadened when the cylinders are more closely arranged, a shallower OWC draft obtains better wave energy conversion with a similar wave protection level, and the wave height has a relatively minor impact on both wave protection and wave energy conversion. In the practical application of wave-energy-utilization type cylindrical open breakwater, relatively small cylinder spacings and OWC drafts are suggested, taking better wave protection and wave energy conversion into account at the same time.
