Outline of Final Research Achievements

Hydro-VENUS is the flow-induced oscillation based tidal energy converter using a physical pendulum. This study aims to improve the energy harvesting performance of Hydro-VENUS by increasing self-exciting force acting on the pendulum. As a result of improving the pendulum cross-section shape, it is found that the cross-section shapes which induce galloping oscillation are effective in causing strong oscillation and increasing the self-exciting force. Multiple pendulums arranged closely in parallel rows can improve the energy harvesting performance of Hydro-VENUS efficiently.
