A new vertical axis wind turbine of savonius type has been designed, constructed, and tested. This turbine has been designed and constructed to operate in low wind speed and it can capture wind at any direction or condition due to the shape and design of the rotor blade and the guide vanes. The wind turbine model has rotor radius of 300 mm and rotor height of 600 mm. After constructing the wind turbine for the experimental purpose, tests were carried out to measure and evaluate the performance of the rotor. During the testing, the parameters that were measured are wind speed, rotor speed, and rotor torque. Two experiments were conducted; the first experiment were carried out to measure the minimum starting wind speed of the rotor while the second experiment was carried out to evaluate the rotor performance based on its torque and power at different wind speed. For each experiment, the rotor parameters were measured when the rotor are constructed with and without the guide vanes. The experimental results were compared with both theoretical results of the model and with an ideal output of common savonius rotors. The experimental result shows that the turbine can operate at low wind speed (1m/s) at zero loads. At wind speed of 5.6 m/s ,the rotor were able to Produce maximum torque of 0.14 N.m, maximum Power of 1.6 Watt, and rotor speed of 100 RPM. Based on the rotor torque and power coefficients, the rotor is capable of producing higher torque than common savonius rotors but with lower tip speed ratio. The high torque of the rotor is because of the functionality of the guide vanes in minimizing the negative torque effects which is common problem for savonius rotors. However, the comparison between this rotor and other common savonius rotors might not be an accurate indication of the rotor capability because this model has six blades while common savonius rotors are of two or three blades. 1997 Thesis http://eprints.utm.my/id/eprint/44290/ http://dms.library.utm.my:8080/vital/access/manager/Repository/vital:69029 masters Universiti Teknologi Malaysia, Faculty of Mechanical Engineering Faculty of Mechanical Engineering
