Study on Performance Improvement of the Savonius Wind Turbine for Urban Power System with Omni-directional Guide Vane (ODGV)
Keywords:VAWT, Savonius wind turbine, urban area, ODGV
The performance of a Savonius wind turbine was studied for urban power system application. The aim of the study was to analyze the effect of Omni-Directional Guide Vane (ODGV) on rotor performance. The wind tunnel experiment had been carried out on a Savonius rotor model. The ODGV was placed around the Savonius rotor in order to increase the ambient wind velocity to the wind turbine. The tests were performed at a different ODGV slope angle and incoming wind direction. The maximum power coefficient (Cpmax) obtained was 0.125 at 60o wind direction. The maximum power coefficient of a Savonius wind turbine with ODGV was 21.46% higher than the Savonius wind turbine without ODGV. The result showed that the ODGV had the potential to increase the performance of the Savonius wind turbine.
