ABSTRACT

 

Innovative work exercises in the Field of renewable energy have been significantly expanded in numerous nations as of late, because of the overall energy catastrophes. Wind energy is turning out to be especially critical. Albeit extensive advancement have as of now been accomplished, the accessible specialized configuration is not yet sufficient to create solid wind energy adapters for conditions relating to low wind speed and civil zones. The Savonius wind turbine seems, by all accounts, to be especially encouraging for such conditions, however it still have a poor efficiency. In this project, we intent to improve the efficiency, output power of the Savonius design by rising the blades number from two to three blades and adding belt transmission system in order to achieve the previews three aims. In order to select the best geometry for the design we made a comparison among different VAWT concepts and by using Quality Function Deployment (QFD) we have chosen the three blades concept. We used the Pugh matrix in order to select the material of blades which it is hot rolled Aluminum sheet with 1 mm thick. The predicable output power after calculating the mechanical loads on shaft, bearings, blades and gears is in range of {50-60} Watt. The maximum obtained capacity is 0.16% which it's close enough to ideal capacity 2% according to the Betz limit Law. The report concludes that this project could be applied in Northern Cyprus, because it’s cost effective, availability of the required materials and the suitable wind stream to take advantage of micro wind turbines.
