Kajian Eksperimental Pengaruh Jumlah Sudu Terhadap Torsi Dan Putaran Turbin Savonius Type U

Edit
Abstract: Wind energy is one type of energy that is expected to reduce our dependence on fossil fuels, which are increasingly reduced in number, in the utilization of wind turbine technology is required conformity with the characteristics of wind turbine where it is used. For it has been tested against U-type Savonius turbine with two blades and three rotor blades, to determine the effect of rotor blade against rotation and torque and power that is able to produce. Test results showed that: At no load condition, the rotor blades savonius two starts spinning at a lower wind speed (0.5 m / s) and has a rotational speed higher than the three rotor blades at the same wind speed. Three blade Savonius rotor was started generating torque and power at lower wind speeds (1.8 m / s) than the two rotor blades and produces more power at the same wind speed. Power that can be raised Savonius rotor diameter of 40 cm and a height of 60 cm on average wind speed - average Indonesia (<4.5 m / s) was very small and unable to produce the expected energy. To take advantage of wind energy as wind power plant with a Savonius rotor type N, it is suggested that using a rotor with larger dimensions and the number of blades is more, according to the diameter of blade.
