Summary:
The need to increase the energy efficiency and energy harvesting of vertical axis wind turbines is growing as a consequence of the quick expansion in the energy sector. Therefore, it is crucial to comprehend how a turbine operates. In this study, the more often used VAWT—vertical axis wind turbine—has been experimentally evaluated. Various performance graphs have been produced as a result. At various wind speeds, S1014 and S1020 airfoils are employed. Aspect ratio and angle of attack were noted, and the performance of the turbine was investigated in relation to the impact of the current produced by the turbulence generating plate. The subsonic wind tunnel setup utilized during the testing consisted of a 15 W DC motor and a 0.1 Nm torque meter. The findings demonstrated that the S1014 type blade profile was more efficient and boosted performance of the two types.
