“…A suitable wind turbine development in Indonesia is the savonius vertical axis wind turbine due to the low average wind speed [8]. Savonius wind turbines have high starting torque but are inefficient at low wind speeds [9]. Savonius wind turbines are effective in extracting wind energy and generating mechanical and electrical energy from small scale i.e.…”

Renewable, unlimited and environmentally safe, wind energy is referred to as renewable energy. In Indonesia, wind speeds between 3 to 7 m/s are considered moderate wind speeds. Wind turbines can be used to convert wind energy into electrical energy. The Savonius rotor is cylindrical and has two or more blades attached. The purpose of this study is to determine the power, torque, and rotation per minute produced by a Savonius rotor wind turbine with a blade radius of 50 cm and a blade height of 100 cm. Wind speeds of 3 m/s, 5 m/s, 7 m/s, 9 m/s, 11 m/s, 13 m/s, and 15 m/s were used for testing. A tachometer was used to measure rpm, while a loadcell sensor measured torque and power data. Based on the research findings, it was found that each wind speed variation produced a different average rotor rotation per minute. The rotor speed, torque, and power increased with increasing wind speed.

This study aims to overview the ability of ventilated blades to improve the performance of the Savonius rotor based on CFD simulation. Rotor performance is analyzed by static torque, pressure profi le, a airfl ow profi le and vortex area. The boundary conditions for all simulations use the assumption that the wind speed is 5 m/s and the environmental pressure is 1 atm or 101325 Pa. The CFD simulation results have strengthen the published experimental results. Ventilation with the 5% gap width of blade diameter (the SV05 model) gives the best performance. Static torque of SV05 model is 23.8% higher than the conventional Savonius (SC) rotor. Based on pressure and airfl ow profi le of CFD simulation results, ventilation on the blade can add the mass fl ow rate of air and make the lift force work early on rotating angle of 0o and 165°. Ventilation on the blade also able to improve the critical condition and vortex area as seen in the SC rotor. This is shown by a static torque from the CFD simulation results. The static torque value of the SV05 rotor are 69% and 73% higher than the SC rotor at the 165° and 0° rotation angle.
