To prevent the global warming, it is desired to develop eco-friendly electricity generating methods. For this sake, various types of generating methods utilizing renewable energy, such as, wind power and solar power, have been already developed and are in operation. But it seems very important to increase the diversity of the electricity generating methods. In this study, fluid-elastic vibration of tubes subjected to cross flow will be utilized. Fluid-elastic vibration sometimes causes the failure of tubes in the heat exchangers such as a boiler and a steam generator. Conventional researches focus on the methods to suppress this vibration. But if we focus on this vibration from the other aspect, this vibration has very large energy, because tubes take in energy very efficiently from fluid. Therefore, we propose a new method to generate electricity from fluid-elastic vibration of tubes. Here, we fabricate a fundamental flow-induced vibration model of tubes and investigate the possibility to harvest energy and to generate electricity from fluid-elastic vibration.We employ electromagnetic induction as generating electricity.
