Kajian Eksperimen Pengaruh Berbagai Sudut Deflektor Di Samping Advancing Blade Turbin Angin Savonius Dengan Myring n=1

Abstract

Indonesia had a big potential for wind energy to be changed into electrical energy. Savonius wind turbine is one type of turbine that can convert wind energy into electrical one. Various previous studies had stated that additional deflector can improve the turbine performance. The coefficient of power (Cp) and coefficient of torque (Ct) values can still be increased to be optimum. This experiment used a turbine with a diameter of 40 cm and a height of 40 cm with myring n=1. The deflector length is 50 cm and height is 40 cm. The wind speed variations are 5 m/s, 6 m/s and 7 m/s. The angle variations used are 15^o, 30^o and 45^o. The deflector is placed next to the advancing blade with Myring n = 1. After the experiment ended, the result shows that the best value of Cp is 0.270 at TSR (tip speed ratio) 0.587. It is obtained at an angle of 15^O. The best value of Cp is 0.689 at TSR 0.119 and obtained at an angle of 45^O with  6 m/s wind speed.
