Abstract

Indonesia has a huge hydro energy potential, but the installation is still relatively small. This fact shows that hydro energy as a power plant still needs to be developed. Many studies concerning water turbines as supporting the development, one study on the performance of the turbine Savonius water. Simulation research is one way to accelerate the research process towards increasing the efficiency of the savonius water turbine. In this research, the effect of overlap ratio and number of blades on the performance of the water turbine savonius has been carried out. The study was carried out in a numerical analysis using computational fluid dynamic approach. The study began with a mesh independence study to obtain effective mesh. The research was simulated in 3 dimensions. Aspect Ratio used in this research is 1, with variations in the number of blades 2, 3 and 4. Variations used overlap ratio 0.1, 0.2 and 0.3. The factors that have been studied are TSR, Overlap Ratio, and Number of Blades. Where the influence of these factors was analyzed using the Factorial Design method
