In this paper we propose a new type of bidirectional and Double Rotor turbine, for OWC. It is combined Wells and Impulse rotors. These are set concentrically each other for the purpose of high efficiency and good starting characteristic. We describe a concept and performances of the turbine examined with numerical simulations. The results show that a maximum efficiency of the turbine is obtained at low flow coefficient, which is advantage to generate electricity. They also show large torque coefficient at high flow coefficient, which is advantage for starting characteristic. However the maximum efficiency is smaller than the conventional Wells and Impulse turbines at present.
