해류발전 로터의 개발

초록

In this research, a design guideline of current generating rotor and acceptable field rotor in offshore environment is proposed. To design rotor model, wind mill rotor design principles and turbine theories were applied based on a field rotor experimental data. To verify the compatibility of the rotor design method and to analyze the properties of design factors, 3 rotor models were designed and experimented in a circular water channel. Three rotor models were designed according to different blade numbers and blade shapes. With various flow velocities and rotor rpm, the rotor power and efficiency were measured and the properties of rotor were estimated. The results can be effectively applied to the design of current generation rotor.
