Abstract

<p>The objective of this study is to improve output performance of VAWT using Magatama blade. The method improving output performance is to place three guide vanes. The guide vanes were placed around upstream of VAWT. This study compared the performance of VAWT with the guide vanes with that of VAWT without the guide vanes in the experiment. The evaluation methods are to refer to the torque coefficient and the power coefficient. The experiment showed the guide vanes increased the torque coefficient about 3 times higher than that without guide vanes. The experiment shows the guide vanes increased the power coefficient about 6 times higher than that without guide vanes.</p>
