Basic sketch of Savonius wind rotor Basic equations . It works relatively at low . It consists of two to three "scoops" that employ a drag action to convert wind energy into torque to drive a turbine. So, normally the design limit of RPM would be just the maximum RPM for maximum designed wind speed (faster wind, and the unit may self destruct if no brake). In this project, a two-blade Savonius wind turbine has simulated using sliding mesh in Ansys Fluent software, and then the results were investigated. Savonius wind turbine which firstly developed by Sigurd J. Savonius in 1922 is a drag type turbine that is relatively suitable for low wind speed as in Indonesia. The Savonius turbine-based design catches wind from all directions, creating smooth powerful torque to spin the electric generator. The choice for this model is to The savonius wind turbine has an ability to self-start [8] and able to generate torque due to the drag force of its own geometry, but the efficiency is (20%) lower than darrieus rotor [9]. The wind turbine that [Greg] designing is a Savonius-style wind turbine that would put out between 5 and 12 volts. The aim of this work is to design and develop a new Savonius type vertical axis wind turbine which uses wind flow from vehicle and convert it into electrical energy for small scale energy applications. 2. A Finish engineer Savonius introduced the Savonius rotor in 1920s. A Savonius turbine is a drag type wind turbine while a Darrieus turbine is a lift type turbine. So, Savonius vertical axis wind turbine can be a better option as it operates in low wind conditions also. The Savonius rotor has two blades with the highest power coefficient, only 0.15, at a tip speed ratio of 0.69 (Kailash et al., 2012). 1-3 show the tested turbines and various design parameters of these turbines are given in the Tables 1-3.
