- D203 Control of angle of attack for Darrieus blades by cylindrical elements
抄録
Since Darrieus turbine is omnidirectional against the wind, it has a great essential advantage in turbulent wind environment. However, the disadvantage is known on the starting up in low velocity conditions of the wind, compared with Propeller turbines. In this study, a new technique to improve the efficiency is proposed by providing a large internal cylinder rotating together with the blades, which can control the angle of attack of the blades. The influence of cylindrical diameter on the blade performance is evaluated from the wake of the turbine. The flow field around the blades is measured by Particle Image Velocimetry. Moreover, the change of angle of attack and lift coefficient are calculated from the measured relative velocity vector field. As a result, the change of angle of attack and lift coefficient are improved in a limited range of rotating angle.
