Abstract: The Savonius wind turbine is a vertical axis wind turbine that works well in relatively low wind speed. Unfortunately, the Savonius wind turbine has relatively low coefficient of power (Cp). Modified designs have been done and studied to increase the performance of the turbine. The purpose of this research is to study the influence of vertical fins addition to performance of the modified Bach type wind turbine. The research was done by 2 dimensional of computational fluid dynamics (CFD) modeling and Ansys Fluent commercial software was used to solve model. Original modified Bach type wind turbine was compared to the modified ones with the addition of one and two fins. The models were simulated on various tip speed ratio, to find out the Cp profile of the wind turbine. The result shows that the best Cp was obtained by adding a single fin to the turbine and compared to the original turbine it increases by 8.81%.
