摘要：
This paper aims at identifying the characteristics of the Savonius Wind Turbine using a guide vane, which functions as the steering mechanism and reduces the negative torsion on the returning blade. The addition of the guide vane did not influence the turbine’s capacity in receiving wind direction. The number of guide vanes varied from 4, 8, and 16 with an angle of 45°. The testing was conducted in a wind tunnel at the wind speeds of 4 m/s, 5 m/s and 6 m/s. The turbine with the additional 16 guide vanes gave the best result. The static torsion increased by 84%, dynamic torsion increased by 57%, and the coefficient of power increased by 58% at the speed of 4 m/s. © 2020, Turbomachinery Society of Japan.
