STUDI NUMERIK PENGARUH VARIASI SUDUT STAGGER SILINDER SIRKULAR PADA SISI ADVANCING BLADE TERHADAP PERFORMA TURBIN AIR SAVONIUS TIPE MYRING
Savonius water turbine is a type of vertical shaft turbine which has the advantage of being able to work on low fluid flow speeds and has a high initial torque, making it suitable for use in rivers or irrigation channels available in Indonesia. The study in the previous research was to analyze the flow of the Savonius wind turbine modified with Myring Blade using CFD. The simulation results show that the Rotor with blade n = 1 has the highest power coefficient, 0.2573, which is 10.98% higher than conventional Savonius turbines. In another study, modifications were made by adding a circular cylinder on the advancing blade side so that the velocity of fluid flow leading to blade advancing made the positive torque produced by the turbine increase, the increase in CPmax was 18.04% at TSR 0.7 so turbine efficiency increased. The method used in this study is numerically with simulated domain size inlet 6D length, 15D outlet, upper side length and 550mm lower side from the turbine center. Modifications are made with the type of myring n = 1 blade and the addition of a circular cylinder so that the speed of fluid flow leading to blade advancing is higher, so that it is expected to increase turbine efficiency. The angle of placement of the barrier cylinder is varied every 15o with a range of 0o90o. The ratio between the diameter of a circular cylinder and the diameter of the rotor is varied in the values of 0.2, 0.3, 0.4, 0.5. The study was carried out on an external stream with Reynolds number 1.1 × 105. From these variations, it will be known the effect of variations on the myring n = 1 Savonius water turbine and the highest torque and power coefficient for water turbines
