Abstract

<p>In this study, a new blade which has a Magatama-type section for VAWT is proposed. This blade can be operated under low wind speed and low tip speed ratio circumstances. Double blade turbine is proposed to improve power coefficient. Double blade turbine is searched arrangement angle of blade and angle of blade which become max power coefficient. It is found from the numerical analysis and the wind tunnel experiment that the double blade turbine generates 4.6 times larger power coefficient as compared with the former blade wind turbine.</p>
