The utilization of wind energy as a renewable alternative is increasingly important as fossil energy reserves are depleting. This study evaluates the performance of a Savonius-type vertical wind turbine equipped with a deflector at three angles (0°, 30°, 60°) and three wind speeds (11 m/s, 12 m/s, 13 m/s). Experimental tests were conducted in the WT-40 Subsonic wind tunnel; measured paramete…
