Abstract

Flow analysis across Savonius turbine with the addition of the circular cylinder before the flow touch returning side of turbine is performed. This project investigates the effect of distance (y) of the cylinder position using CFD, where the displacement of the circular cylinder perpendicular to the direction of the incoming flow is called distance of y. Numerical study is carried out by using moving mesh with 2 zones namely the stationary and rotating zone with Reynolds number (Re) in about 1.1 x 10-5. This research uses circular cylinder as disturbance to improve the Savonius performance by varying y/D of 0.0, 0.25, 0.5, and 0.75. The result reveals that a circular cylinder can increase the performance and the best result occur at y/D of 0.75. The performance increases in about 22.267%
