尾流干涉下圆柱流致振动的俘能实验设计

Experimental Design of Energy Capture Based on Vibration Induced by Cylinder Flow under Wake Interference

为了证实海洋圆柱结构流致振动中蕴含的能量利用潜能,提出了直立式流致振动俘能系统以期有效提升能量俘获效率,并设计了相关实验。确立了振动圆柱不同的布局形式,在随机波流耦合水槽中对不同布局下圆柱的尾流干涉效应展开了研究,并结合流致振动实验中的圆柱尾流激振响应现象设计了直立式流致振动俘能实验。相关的实验操作与分析强化了学生对基础理论知识的理解,同时提升了学生的学科融合视野与创新实践能力。

With its advantages of green environmental protection,sustainable development and utilization,marine energy becomes an inevitable choice for future clean energy development and a new direction of energy storage research.In this experiment,different distribution forms of vibrating cylinders are established,and the wake interference effects are studied in a random wavecurrent coupled flume.Furthermore,an upright energy harvesting experiment method is proposed based on the wake excitation response of a cylinder in the flow induced vibration experiment.The experiment innovatively combines the fluid vibration of the cylinder with energy harvesting,consolidates and strengthens students’understanding of basic theoretical knowledge,and enhances students’vision of discipline integration and innovative practical ability.
