Design and analysis of a small wind turbine with combined airfoil

The purpose of this article is design and analysis of small wind turbine. To this aim¡ the Marvast region in Yazd province is selected as the design pilot region. Wind turbine is consisting of some components and the proper airfoil design is one of most significant issues. In this work two types of airfoils are combined that one airfoil has the proper starting torque and the other one has the high efficiency. The output airfoil is a J-shape airfoil that is the combination of Savonius and Darrieus airfoils. Design is analyzed using the software and the effect of parameters is investigated.
