Multi-Objective Optimization and Optimal Airfoil Blade Selection for a Small Horizontal-Axis Wind Turbine (HAWT) for Application in Regions with Various Wind Potential

The type of airfoil with small wind turbine blades should be selected based on the potential area in which is used. In this study, 10 low Reynolds number airfoils, namely, BW-3, E387, FX 63-137, S822, S834, SD7062, SG6040, SG6043, SG6051, and USNPS4, were their performance was evaluated a 1 kW terms power coefficient also startup time, by performing multi-objective optimization study. blade element momentum technique utilized to perform calculations time differential evolution algorithm employed carry out optimization. results reveal that used blade, aside from aerodynamic performance, completely affects performance. SG6043 has highest BW-3 presents shortest time. high lift-to-drag ratio inertia fitted make them suitable for operation windy regions areas speeds, respectively.
