Abstract
The purpose of this study was to design and build a micro vertical axis wind turbine (TASV) and optimize NACA 0012 blades with various angles of attack to obtain optimal performance. Measurement variables are worked out by developing an Arduino-based digital measurement system. The method used in this study was to collect data directly from the wind tunnel, by preparing 2 sets of NACA 0012 airfoils from angles -5°, 0°, 5°, 10°, 15°, 20°, 25°, 30°, and 35°. Parameters to be measured include: Number of blades, Turbine rotation speed, Wind speed, Power, and several parameters to be calculated include rotation efficiency, Cp (performance coefficient), and TSR (Tip Speed ratio). The test results show that in testing with a wind speed of 10 m/s the number of blades 1 and 2, the optimal turbine rotation with 1 blade is at a 15° angle of 700 rpm, while the optimal turbine rotation with 2 blades is a 15° angle of 3935 rpm, then the operation turbine with generator using 2 blades with optimal angle is 15° at 1530 rpm rotation. Optimal power with multimeter measurement at 2 blades of wind speed 10 m/s operation and 15° angle of attack obtains 0.124 W of power. For Arduino-based measurements at an angle of 15° is 0.125 W. Power efficiency seen from rotation with and without the best generator is obtained at an angle 25° with a rotation efficiency of 42.072%. Cp at an angle of 15° with a wind speed of 2.5 m/s of 0.00042 and a TSR of 0.931. Whereas at a wind speed of 5 m/s the TSR is 1.043 and Cp is 0.00704, the wind speed is 7.5 m/s resulting in a TSR of 1.178 and a Cp of 0.019, a wind speed of 10 m/s a TSR of 1.281 and a Cp of 0.018.
