STUDI NUMERIK PENINGKATAN KINERJA TURBIN AIR ROTOR SAVONIUS SUMBU HORIZONTAL
Savonius turbines have two sides that are concave and convex shape so that the turbine rotors form to resemble the letter "S". This turbine needs an increase in efficiency due to the lack of obstacles received by the turbine. Savonius turbine performance will increase if the obstacles on the turbine get bigger. Previous studies examined the addition of the steering plate to increase the power coefficient (Cp) and torque coefficient (Ct). In this study, the steering plate will be added to the curve and change the angle of the steering plate to get better turbine performance improvement. On the steering plate variations in the angle of the curve of 0o, 20o, 40o and 60o with varying tip speed ratio (TSR) will be added. Water turbine modeling is done by using a uniform fluid flow in each part so that vorticity can be detected around the rotor and hydrodynamic forces that work. The turbine is placed near the wall and the rotor rotates clockwise. The steering plate is placed in front of the rotor so that fluid collects in the rotor. From the simulation results obtained, the curve of the steering plate will reduce Cp. Changing the angle of the bottom steering plate can increase the Cp of the water turbine, increasing the TSR will increase the turbine power coefficient and the torque coefficient will decrease
