摘要：A vertical axis wind turbine model having three frames with cavity vanes has been designed, fabricated and tested in a low speedwind tunnel. This type of model has a high drag coefficient when the vanes close the frame on one side while rotating with wind directionand capturing the wind efficiently. On the other side, the frame rotates in the opposite direction of the wind which opens the frame causingthe wind to pass through the frame with low resistance. The model is tested in a wind tunnel with the wind speeds varying between 3 m/s and17 m/s. The present model gives the maximum power coefficient of 0.32 at a wind speed of 8.2 m/s and tip speed ratio of 0.31 which is higherthan those of the vertical axis wind turbines in the literature for the purpose of comparison. The performance of a similar prototype VAWThaving a scale ratio of 10:1 is also predicted using the dimensional analysis.
