Manufacture and Testing of the U-Type Savonius Wind Turbine with 4 Blades Vertical Axis

Abstract

This research focuses on the design, fabrication, and testing of a 4-blade vertical axis Savonius wind turbine with U-shaped blade types. The purpose of this study is to evaluate the performance and efficiency of turbines in various wind conditions. The turbine design involves utilizing a vertical axis configuration, which allows simplicity in construction, ease of maintenance, and adaptability to changes in wind direction. The U-shaped turbine blade configuration improves torque generation, leading to better power output. To make a turbine, the right materials and components are needed, and the manufacturing process is carried out carefully so that the turbine has good performance. The dimensions and dimensions of the turbine are determined by a diameter of 0.3 meters and a height of 0.5 meters. A series of experiments were carried out to evaluate the turbine performance under different wind speeds. Generator power output, turbine rotation, and torque generated by the turbine are measured and analyzed. From the tests carried out at a maximum wind speed of 10 m/s it produced a turbine rotation of 296 rpm and a generator power of 20.3 Watt, a power coefficient of 0.0311 with a TSR value of 0.464, and a system efficiency of 7.25%.
