摘要 In this study, wind tunnel experiment has carried out to investigate the selfstaring capability for straightbladed vertical axis wind turbine. The flow visualization has also been performed at the rest of the rotor. The effect of the azimuthal angle of blade position relative to wind direction on the selfstarting capability was discussed based on the results of flow visualization. The torque and the centripetal force of the rotor when the selfstarting behavior starts were roughly calculated by using the result of flow visualization of the rotor. It was suggested that there exist the condition of wind speed and configuration of the blade position of the rotor at the rest of rotor to the reach to situational rotation number.
