Throughout human history major advances in culture have always been
followed by increasing energy consumption. Hydrokinetic energy can be used in
Savonius turbines, with the density of water greater than the density of air, the
Savonius hydrokinetic turbine can extract sufficient kinetic energy even at low
water flow rates. The purpose of this study is to determine the static torque and
dynamic torque generated from the two-level Savonius turbine type bach type
bach. The hydrokinetic turbines studied were three-level Savonius type bach
turbines with varying first and second levels (15 cm: 15 cm, 17 cm: 13 cm and 20
cm: 10 cm) at the same total turbine height. The aspect ratio dimensions are 1.1,
0.2 overlap ratio, rotor height (H) 0.3m, rotor diameter (D) 0.33 m, turbine
diameter (d) 0.3 m, and with variations in water flow velocity ( V) 0.34 m / s and
0.51 m / s in the water tunnel. Both of these torsions are obtained in stationary
conditions (static torque) for each azimuth angle and moving conditions (dynamic
torque) of no load and until they stop rotating. By utilizing the braking force on
pulley with variations in loading. Based on the data obtained from the research of
Savonius turbine type bach three blades double stages using the directive blades
produce at an angle α30˚: β10˚ on the 15/15 turbine get a greater dynamic torque
compared to research with turbines 17/13 or 20/13 that is equal to 0 , 3 Nm at a
water velocity of 0.51 m⁄s, but compared to the results of the dynamic torque
produced by the variation of the directional plate at an angle of α 30˚: β 10˚ and
angle α 45˚: β 10˚ get a smaller result that is 0.288 Nm and 0.252 Nm, the largest
dynamic torque is 0.42 Nm and the static torque is 0, 528 Nm at a variation of 15
cm: 15 cm. From the results of the static torque, the Savonius turbine bach type
three blades with variations of the directional plate at an angle of α60˚: β10˚ get
a static torque greater than the variation of the directional plate at an angle of α
30˚: β 10˚, angle α 60˚: β 10˚ , which is equal to 0.3 Nm and 0.27 Nm, 0.264 Nm.
Keywords: Savonius turbine, static torque, dynamic torque.
