ANALISIS EKSPERIMENTAL KINERJA TURBIN ANGIN DARRIEUS NACA 0025 DENGAN TIGA SUDU

This study presents an experimental analysis of the performance of a three-bladed H-rotor Darrieus wind turbine employing a NACA 0025 airfoil, as an effort to develop a renewable energy–based power generation system suitable for low wind speed regions. The objective of this research is to examine the effect of wind speed variations on wind power, generator power output, and overall system efficiency. Experimental testing was conducted at the Fundamental Phenomena Laboratory of Mechanical Engineering, Universitas Sriwijaya, using a wind tunnel to ensure controlled airflow conditions. The turbine was designed with a height-to-diameter (H/D) ratio of 1.17, a blade height of 21 cm, and a rotor diameter of 18 cm to achieve a more uniform aerodynamic force distribution and stable rotational performance. Wind speed variations applied during the experiments were 8.3 m/s, 9 m/s, 10.2 m/s, 11.3 m/s, and 12 m/s. Measured parameters included wind speed, turbine rotational speed, electrical voltage, and current. The experimental results indicate that both wind power and generator power increase proportionally with rising wind speed. The maximum wind power of 37.55 W and generator power of 5.71 W were obtained at a wind speed of 12 m/s. However, the overall efficiency exhibited a decreasing trend at higher wind speeds, with the highest efficiency of 23.7% achieved at 8.3 m/s. These findings demonstrate that the three-bladed Darrieus wind turbine with a NACA 0025 airfoil performs optimally at low to moderate wind speeds and shows strong potential for small-scale power generation applications in Indonesia.
