Abstract

The Savonius turbine has advantages, including a simple design, unfettered incoming wind direction, can spin at low wind speeds, and start rotation without additional equipment. However, this turbine design has low efficiency, so many researchers have tried to improve it. The primary research in this report is one of the efforts to upgrade the performance of the Savonius turbine in the category of adding external devices experimentally. An I-65° cylinder type with diameter d/D = 0.5 is placed upstream of the Savonius convex blade at a distance S/D = 1.4 with a staggered angle −10° ≤ α ≤ 40° at Reynolds number Re = 10.3 × 10⁴ correspondence to freestream velocity U = 5 m/s. The performance of the standard Savonius turbine will be compared with a turbine that has installed a cylinder type I-65° upstream convex blade based on the power and moment coefficient. The static moment also is compared to identify the self-starting ability. The experiment results show the stager angle α = 40° as the optimal angle with an increase in the coefficient of power of 12%. For static torque measurement parameters, the results also show an increase in performance where the turbine rotation angle with negative torque decreases.
