抄録

In this paper the relationships between power augmentation of the HAWT due to Mie type tip vane application and other factors influencing the efficiency of a wind turbine such as blade aspect ratio, number of blades, blade pitch angle and Reynolds number are investigated. Experiments have been carried out in a large scale wind tunnel. Rotor models used are respectively 2 and 3 blades wind turbines and 4 sets of blades with different aspect ratio have been experimented. For an existing rotor without Mie vane, a maximum power augmentation about 14.5%, due to Mie vane application, is achieved. The relationships between power augmentation by Mie vane and the above factors are investigated. It is found that the application of Mie vane is more efficient in case of rotors with small aspect ratio and for low wind speeds. Surface oil-film and surface tuft visualization methods are used to detect the flow patterns at the blade tip. Attaching Mie vane, improved flow around blade tip is evidenced.
