| Research Abstract |
Since the floating type current turbine can be installed beneath the sea surface, it is possible to construct it in very light weight compared with other marine energy devices installed on the sea surface such as floating wind turbines and wave power generators, and it is one of promising concepts for reducing the construction cost because of its weight. A contra-rotating turbine concept and a twin turbine concept are proposed as the floating type. In order to investigate the performance of these concepts, a simulation code has been developed, and it is validated by model experiments. It is concluded that both two concepts have possibility to be realized and produce low cost electricity.
