Design and Analysis of Savonius Vertical Axis Wind Turbine

A Savonius rotor (S-rotor) wind turbine adapted for household domestic Electricity generation. The design process and justification of the new machine will be described. The innovative technology turbine collects wind energy and converts it into electricity, which in turn produces an output which is used to charge one heavy duty battery. As a result, the home is served simultaneously by the wind turbine and the utility. In this study, a small electricity generator has been specifically designed for household installation. We are using a savonius rotor. This type of rotor (which is of the vertical axis variety) is chosen instead of a horizontal axis machine due to its simplicity and reliability. The S-rotor has been designed using an analytical method and confirmed by natural wind testing. This study was done to investigate the design and development of the vertical axis micro wind turbines. The contribution of counter rotating impellers with a freely rotating generator to produce energy was investigated. For the analysis and design, PRO-E, CAE programmes were used. Possible developments were considered.
