摘要：
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. © 2022, Solar Energy Periodical Office Co., Ltd.
