Abstract: This work experimentally studied the influence of guide vane design to increase Savonius rotor performance. Guide vane is one of additional device that its function is for directing wind stream on to concave blade and deserves as obstacle of the wind that flowing on to convex blade. That way increased wind speeds to the rotor, consequently it produced higher power coefficient and the Savonius rotor performed better performance. Four designs of guide vane were arranged in this study. They are basic design of guide vane and basic design of guide vane that added a tilt angle on the top and bottom sides by 15°, 30°, and 45°. The result concludes that guide vane affects the performance of Savonius rotor. The power that generated by the rotor with guide vanes increase significantly compared with Savonius rotor without guide vane. The maximum improvement was attained up to 65.89%.
