ELSADIC SALIM .A. MOHAMED, Student Number: S951208505 A STUDY OF THE INFLUENC OF GUIDE VANE DESIGN ON SAVONIUS WIND TURBINE PERFORMANCE. Supervisor I: Dr. Danardono Dwi Prija T, ST, MT, Ph.D. Supervisor II: Dr. Dwi Aries Himawanti, ST, MT. Thesis: Mechanical Engineering Department, Graduate School of Sebelas Maret University. 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 to direct wind stream onto concave blade and deserves as obstacle of the wind that flowing on to convex blade. This method increased wind speeds to the rotor, consequently it produced higher power and the Savonius rotor performed better. Four designs of guide vane were arranged in this study. They were 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 concluded that guide vane affects the performance of Savonius rotor. The power that generated by the rotor with guide vane increases significantly compared with Savonius rotor without guide vane. The maximum improvement was attained up to 65.89%.
