摘要:流致振动现象是典型的流固耦合现象,其在空气动力学、水动力学及海洋动力学中均有涉及。近年来,随着流致振动发电设备的不断涌现,学术界又掀起了新一轮的流致振动研究浪潮。目前,有关流致振动发电的研究内容纷繁多样,并未形成系统的研究体系,因此有必要对流致振动能量利用现状及存在的问题进行系统的整理与分析。首先,详细梳理了圆柱绕流及非圆柱绕流的流致振动研究现状,指明了流致振动能量汲取在海流及风能利用上的巨大潜力;随后,基于现有的研究成果介绍了近几十年来主要的流致振动发电设备的种类、工作原理及应用现状;然后,基于现有的流致振动发电理念全面阐述了流致振动能量转化的研究现状,并剖析了研究当中存在的各类问题;最后,对流致振动能量利用的研究方向提出了建议。

Development and prospect of study on the energy harness of flow -induced motion

LIAN Jijian ,YAN Xiang ,LIU Fang (State K e y L aborator y o f H y draulic En g ineering Simulation and Sa f ety ,T ian j in Universit y ,T ian j in 300072,China )Abstract :Flow -induced motion (FIM )is a typical fluid structure interaction (FSI )p henomenon ,and is involved in aerodynam -ics ,hydrodynamics ,and ocean dynamics .Recently ,as lots of FIM power convertors emerged ,the study on FIM thrived again .Until now ,there are lots of unsystematic directions in the research of FIM and its energy conversion .Thus ,it is necessary to systematically analyze and discuss the situation and the problems in this research field .To this end ,four parts are summarized and discussed in this study .First ,the current situation of the study on the FIM for circular and non -circular cylinders is summa -rized .This paper points out that capturing the energy from FIM greatly benefits the utilization of current and wind energy .Then ,it introduces the types ,working principles ,and applications of the main FIM power convertors in recent decades .Further -more ,based on the theories of FIM ,it introduces and analyzes the current situation of FIM energy conversion research ,and dis -cusses the problems in the research .At last ,some suggestions are proposed on the future study of FIM energy conversion .
