Abstract
The paper is based on wind tunnel (WT) experiments on experimental models (EMs), vertical axis wind turbines (VAWT), Savonius (SWT, "S" Turbine). The experimental models had the maximum dimensions: height of 0.395 m, and diameter of 0.150 m. A study was conducted concerning the behavior of the EM experimental models for the level (1L) and three levels with a pair of blades (1PB) and a level with two pairs of blades (1L - 2PB). Wind speeds ranging from 0 to 2 m/s were used. Test section of the wind tunnel was 0.5 m x 0.5 m (0.25 m2) and a shutter coefficient of 0.23. Experiments performed confirm the SWT's good behavior at low wind speeds and the possibility of being used to generate low-power electric power with DC generators.
