Effect Of Deflector Angle Into Various Blades Configuration Of Single Stage Vertical Axis Savonius Hydro Turbine Performance

Abstract

Today, the exploitation of energy leads to renewable energy. One of the renewable energy is water flow energy. The Savonius Hydro Turbine is a type of water turbine which is suitable for low flowing velocity. One method for increasing the performance of the Savonius Turbine is by using a deflector. This study aims to see the effect of using a deflector on the Savonius Hydro Turbine's performance. The methodology used in this research is testing with variations in the number of turbine blades and deflector angle. The number of turbine blades used was two, three, and four blades, while the deflector angles used were 0°, 20°, 40°, 60°, and 80°. The result shows that using a deflector angle of 80° make turbine inlet flow is better. From the three blades Savonius Hydro Turbine, The best performance is obtained on 80° deflector angle with power 0.154 Watt and coefficient of power 0.132.
