Design of morphing wind turbine blade

In this study, an optimization study was carried out on the blade according to the active stall and various attack angles required on the wing profile for calculating wind turbine blades. In the optimization study, Cl/Cd optimization was used for the k-ε model and ANSYS Fluent Adjoint Solver anda according to the boundary analysis, changes on the wing profile were examined. The first simulation model created in the study was verified with the profile verification data available on the Cornel University Confluence site. In the continuation of the study, symmetrical wing and parallel flow condition which physically lifting force cannot be obtained have been tried. In the continuation of the study, by considering the efficiency of 4º angle of attack 25m/s, which is one of the best points of the wing profile, wing efficiency is optimized according to this point. An increase in the coefficient of buoyancy was observed with the increase in efficiency for the value of 10º attack angle 5m/s and 4º angle of attack 20m/s. In the range of 4º angle of attack up to 25m/s and 4 50 angle of attack up to 50m/s, it moved to reduce the wing profile lifting force for safety reasons. The lift / drag force coefficient ratio, which defines the efficiency value at varying wind speeds and offensive angles, is fixed at Cl/Cd, 13.205625 and is designed to change according to the optimum operating mode. For safety reasons, the wind turbine's energy generation can be prevented by perdovity by using a deformable wind turbine blade, while the wind speed range that the wind turbines can generate energy can be expanded to increase the capacity factor and annual energy production of the turbine.
