Abstract

A Savonius windmill is known for the fact that it will work even the wind blows strongly or weakly. It also can receive the wind of any direction. Its drawback is the lower efficiency compared with other windmills. The main goal of this research is to increase the effciency of the Savomius windmill by findimg out a better rotor bucket shape for concentrators.
