Study of a New Air Turbine for Wave Energy Conversion

파력발전용 새로운 공기터빈 개발에 관한 연구

In order to develop an efficient turbine for wave energy conversion suitable for actual ocean conditions, a new type of the air turbine with staggered blades has been investigated experimentally. Experiments have been carried out under steady flow conditions. Both the running and starting characteristics under sinusoidally oscillating flow conditions are simulated by a CFD method using a quasi-steady analysis. It is known that the air turbine with staggered blades gives a better performance compared with conventional Wells turbine, and a proper design factor of the air turbine is discussed for the setting angle of the rotor.
