| dc.description.abstract | This study aims to analyze the performance generated by the Savonius wind turbine due to changes in blade shape and number of blades. There are 2 blade shapes used, namely the U blade shape and the L blade shape. As for the number of blades used are 2 blades, 3 blades, and 4 blades. The performance of the Savo-nius wind turbine can be seen from the rpm, torque, turbine power, generator power, CP, and TSR produced. In the U blade shape with a wind speed of 7 m/s, the highest shaft rotation (rpm) is obtained in the 3 blade wind turbine which is 74.3333 rpm, the highest torque is obtained in the 3 blade wind turbine which is 0.10236143 Nm, the highest turbine power is produced in the 4 blade turbine of 945.7124 Nm/s, and the highest generator power in the 3 blade wind turbine is 15.667 watts. In the L blade shape with a wind speed of 7 m/s, the highest shaft rotation (rpm) is found in the 3 blade wind turbine which produces 66 rpm, the highest torque is found in the 3 blade wind turbine which is 0.137822197 Nm, the highest turbine power is produced in the 4 blade turbine of 529.7250 Nm/s, and the highest generator power in the 3 blade wind turbine is 17.5667 watts. As the wind speed increases, the rpm, torque, turbine power, and generator power also in-crease. | en_US |
