IMPROVEMENT OF VAWT SAVONİUS TURBİNE MECHANİCAL POWER FOR THE POWER GENERATİON PURPOSES OF SHORE POLES

Abstract

This study presents an improvement in the design of the VAWT Savonius turbine based on changing the swept area to provide better power generation. It is aimed at this design to provide charging poles to be located along the shore. The swept area is designed with a reasonable height and rotor diameter whereas the Savonius rotor is suggested to be made with two semi-circular shapes blades of aluminum that have an acceptable estimated load since this load plays a big role in the rotation of the turbine. In this research, the shaft frequency in rpm is estimated using the artificial neural network (ANN) where the annual wind speed data for different areas in Turkey are used. The Savonius turbine mechanical power calculation results show that different accepted power ranges can be obtained. Considering this design’s simplicity, multiple poles can be planted along the shore areas to provide a charging power supply for small electronic devices. This design is considered to be suitable for this kind of area since it is built with a low cost, does not need a specific wind direction, and can rotate with a low wind speed.
