Pengaruh Variasi Panjang Busur Terhadap Performa Turbin Angin Savonius Persamaan myring n=1 dengan Kecepatan 6 m/s

Abstract

The Savonius wind turbine is a type of vertical axis wind turbine widely used for small-scale applications due to its simple construction and ability to operate at low wind speeds. Previous studies have shown that the addition of deflectors can enhance performance, but the blades used have not been varied. Therefore, this experiment employs variations in arc length with a myring equation of n=1 without deflectors. This research aims to analyze the performance of the Savonius wind turbine with variations in both increased and decreased blade arc lengths of 4 cm and wind speeds of 5 m/s, 6 m/s, and 7 m/s in relation to the torque coefficient and power coefficient produced. The best results from this experiment were obtained with an increased arc length at a speed of 6 m/s. The optimal power coefficient value was 0.2364, with a performance improvement of 28.340%, while the torque coefficient was 0.6118, showing a performance improvement of 12.857% compared to other variations.
