摘要
基于空间共享和成本分摊理念提出一种由振荡浮子式波能装置和浮式防波堤相结合的集成系统,应用计算流体力学方法建立耦合数值模型,并研究集成系统水动力性能,分析动力输出系统(PTO)阻尼、波能装置与浮式防波堤间距、波能装置宽度对集成系统能量捕获和消波特性的影响。结果表明,所提出的集成系统相对运动优于波能装置与固定式防波堤集成系统以及单独的波能装置。PTO阻尼系数的合理选取可使集成系统具有较优的能量捕获和消波性能;间距的减小和波能装置宽度的增加可改善集成系统能量捕获性能,转换效率可达78.5%。
Based on the concept of space sharing and cost allocation,an integrated system combining oscillating buoy type wave energy converter and floating breakwater was proposed,and a coupled numerical model was established by computational fluid dynamics method,and the hydrodynamic characteristics of the integrated system was investigated,and the effects of power take-off(PTO)damping,the gap between wave energy converter and floating breakwater,the width of wave energy converter on the energy capture and wave attenuation characteristics of the integrated system were analyzed.The results show that the relative motion of the proposed integrated system is better than that of wave energy converter and stationary breakwater integrated system and the isolated wave energy converter.The reasonable selection of PTO damping coefficient can make the integrated system get better energy capture and wave attenuation performance.The reduction of the gap and the increase in the width of the wave energy converter can improve the energy capture characteristics of the integrated system,with the conversion efficiency up to 78.5%.
