N2 - Rotating the cylinder increases velocity in the upper and lower sides, increasing velocity between the advancing and cylinder by rotating in the opposite direction. The increase of velocity in the attached flow will decrease the pressure. The total drag will increase, which can improve the performance of Savonius. The study will be done experimentally to obtain the effect of cylinder obstacles at the advancing area of the Savonius wind turbine. The experiment used conventional savonius without overlap ratio having a size of 0.4m in diameter and height. The cylinder diameter ratio used was ds/D of 0.1, 0.2, 0.3, and 0.4, with stationary and rotation of 25 rotations per minute. The experiment would calculate the tip speed ratio, torque coefficient, and power coefficient. The best result obtained is a cylinder with a 0.4 diameter ratio (ds/D), 25 rotations per minute, improving the coefficient of power of 66.193% compared with no cylinder.
