Abstract:
Flow-induced motion (FIM) is a typical fluid structure interaction (FSI) phenomenon, and is involved in aerodynamics, 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 summarized. 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. Furthermore, based on the theories of FIM, it introduces and analyzes the current situation of FIM energy conversion research, and discusses the problems in the research. At last, some suggestions are proposed on the future study of FIM energy conversion.
