Abstract
Recently, environment problems due to the use of fossil fuel, such as global warming, climate change, air pollution, acid rain and many others, are becoming serious. To solve the problem, alternative renewable energy is required. In this paper, we focuses on the effective use of ocean power and have developed a compact, low-cost but flexible floating buoy to generate electric power from ocean wave. In order to optimize the design, we perform fluid-structure interaction analyses to consider the buoy motion without experiments. However, it was difficult to achieve the optimization for the commercial code, ANSYS, because there are many restrictions in ANSYS due to its mesh-based algorithm. Therefore, we originally develop a particle(SPH)-based analysis code.
