Abstract

This study designed, fabricated, and experimentally evaluated a three-bladed Savonius vertical-axis wind turbine for low-wind-speed conditions. The engineering experiment comprised a literature review, specification definition, three-dimensional modeling in SolidWorks, prototype fabrication, and controlled wind-tunnel testing. The rotor used three semi-cylindrical aluminum blades with a blade diameter of 0.60 m, an effective rotor diameter of 1.186 m, a rotor height of 0.96 m, and a swept area of 1.13856 m². Tests were conducted at wind speeds of 3.5, 4.0, 4.5, 5.0, and 5.5 m/s, with rotor speed and torque measured in three repetitions for each condition. Increasing wind speed from 3.5 to 5.5 m/s increased the average rotor speed from 57.80 to 104.27 rpm, torque from 0.40 to 0.80 N·m, and mechanical power from 2.42 to 8.74 W. The tip speed ratio ranged from 1.03 to 1.21, while the mechanical power coefficient ranged from 7.53% to 8.69%, with the maximum mechanical power coefficient of 8.69% obtained at 4.0 m/s. The prototype operated across the investigated low-wind-speed range, but only one three-bladed configuration was evaluated; further optimization of rotor geometry, mechanical transmission, and generator matching is required.
