Studi Eksperimental Pengaruh Bentuk Sudu Terhadap Peforma Turbin Angin Sumbu Vertikal

Abstrak

Energy demand in Indonesia continues to rise alongside industrial and population growth, thereby driving the utilization of environmentally friendly renewable energy sources. Vertical Axis Wind Turbines (VAWT) represent a potential solution due to their ability to operate effectively regardless of wind direction and their capacity to function in areas with low to moderate wind speeds. This study aims to analyze the influence of blade shape on the performance of a VAWT through an experimental approach. The research was conducted by testing three distinct blade models at the Energy Conversion Laboratory of the Faculty of Engineering, University Halu Oleo. The parameters analyzed included rotational speed (RPM), voltage, current, power output, and the coefficient of power (Cp) at wind speeds of 3 m/s, 3.5 m/s, and 4 m/s. Experimental results indicate that blade shape variation significantly impacts the overall aerodynamic characteristics and performance of the turbine. Based on the test data, Model II demonstrated the most optimal performance in terms of rotational speed and power generation across all tested wind speeds. These findings are expected to serve as a reference for developing more efficient and effective small-to-medium-scale vertical axis wind turbines to support renewable energy needs in Indonesia.
