ABSTRACT

 

Among the different vertical axis wind turbine (VAWT) rotor is a slow running wind machine driven by drag force and has a lower efficiency as compared to lift type machine but it is also inexpensive. The present work is to design and develop a modified rotor for low windy regions, to develop a self starting and more efficient wind turbine, which can be used domestically; it is portable and easily fabricated with locally available materials. In this work, Plate profile of the rotor was modified by using 7% of cambered plate which is giving higher efficiency. The rotor is designed and fabricated for application in rural areas for generating electricity.
