Research Abstract

If tidal and ocean current power system can be installed in site where the flow velocity is fast, it may be able to reduce the power generation cost compared with other power generation system. However, suitable sites like this in shallow water around the coast of Japan are restricted. In this study, we investigate a high power tidal and ocean current power system with a multi rotor system. It is important for the tidal and ocean current power generation system to utilize widely in the coastal area of Japan in order to ensure a certain amount of power generated at about 1.0m / s flow velocity. For the multi-rotor system, the back rotor can be collected the flow energy passed from the front rotor. We perform a fundamental study and concept design for multi rotor system.
