Abstract

Savonius have the smallest performance compared by the other turbine and the operational of Savonius at low TSR. In work, numerical analysis was done by using Savonius myring blade n=1 with ANSYS 17.0-Fluent. Flow analysis has been done by adding the circular cylinder. The ratio between the diameter of the cylinder and the turbine blade (ds/D) will be varied 0.2, 0.3, and 0.4. Installation of the circular cylinder with a horizontal distance (X/D) by 0.5 kept constant. The performance at ds/D of 0.4 with TSR number 1 have the highest performance in about 27.21%.
