Experimental performance investigation of electrical energy production system by using vertical barrel of two and five blades from wind energy in Gaziantep condition

Vertical-axis wind turbines (VAWTs) possess several advantages over the conventional horizontal-axis type. Savonius turbines are drag-based routers which operate due to a pressure difference between the advancing and retreating blades. These turbines are simpler in design, less expensive to install, non-dependent of wind direction, and more efficient at lower wind speeds. This makes it suitable for generating electricity in many countries. This work is a study of the performance of the Savonius rotor which contains two and five blades made from barrels of oil under the normal weather conditions of the Turkish city of Gaziantep. This rotor has the best self-starting at low wind speed, under any load generator. Where begins rotation of 20 RPM at 2 m/s wind velocity. We also find the maximum power coefficient at the tip speed ratio and the amount of voltages generated by the generator at different wind speeds to both types and know which one has the best performance. Key Words: Vertical axis wind turbine, savonius, electric power, voltage.
