ANALISIS KINERJA AKTUAL TURBIN ANGIN DARRIEUS TIPE-H ROTOR AIRFOIL NACA 0035

---

Increased demand for electrical energy and limited fossil fuel resources have driven the development of renewable energy, one of which is wind energy. Darrieus vertical axis wind turbines have the potential to be developed in Indonesia because they are capable of operating in variable wind conditions without requiring a wind direction guidance system. This study aims to analyze the actual performance of an H-rotor Darrieus wind turbine with three blades using NACA 0035 airfoil blades. The testing was conducted experimentally at actual wind speeds ranging from 8.1 m/s to 12 m/s using incandescent lamp loads. The parameters analyzed include wind power, generator output power, generator pulley rotation, and overall system efficiency. The test results show that an increase in wind speed causes an increase in current, voltage, rotor rotation, and generator output power. Wind power increased from 11.57 W at a speed of 8.1 m/s to 37.62 W at a speed of 12 m/s, while generator power increased from 2.12 W to 5.77 W. The highest overall system efficiency was obtained at a wind speed of 9 m/s at 18.54%, then tended to decrease at higher wind speeds due to increased aerodynamic losses and generator limitations. The results of this study indicate that Darrieus wind turbines with NACA 0035 airfoils perform quite well at low to medium wind speeds and have the potential to be developed as small-scale power generators.
