摘要
通过理论分析和物理模型实验相结合的方法,系统研究底铰接摆式波浪能转换装置在双向和单向2种不同PTO阻尼作用下的最大功率及俘获效率等水动力性能,同时探究不同浮力摆摆板形式对装置输出功率的影响。实验结果表明:浮力摆在双向阻尼下,装置的能量转换效率和受力特性均优于单向阻尼作用时,建议对底铰摆式波能转换装置施加双向阻尼。
The utilization technology of bottom-hinged flap wave energy converters has attracted more attentions because of its high energy conversion efficiency and structural simplicity.In this paper,the energy conversion efficiency of the bottomhinged flap wave energy converter is systematically studied by physical model experiments and theoretical analyses in the cases of one or two-way power take-off(PTO)damping.In addition,the effects of bottom-hinged flap forms on the output power are also estimated in detail.The experimental results show that the conversion efficiency and mechanical characteristics of the device under two-way PTO damping perform better than that of one way PTO damping.Therefore,in practical engineering applications,it is advisable to exert two-way damping on the bottom-hinged flap wave energy converter.
