Experimental Analysis of Oscillatory Vortex Generators in Wind Turbine Blade

Vortex generators are devices that modify the wind behavior near surface of turbine blades. Their use allows boundary layer shedding transition zone to be varied. Bio-inspired design has been used improve efficiency aerodynamic and hydrodynamic systems by creating shapes present in animals plants. In this work, an experimental methodology is proposed study effect bio-inspired vortex their on structural vibration a blade. addition, wake generated blade with oscillating at different oscillation frequencies analyzed means hot wire anemometer, obtaining appreciable reduction results measured 3D acceleration signals for velocities between 10 15 m/s. Values spectral components velocity higher tunnel increase. Spectral variance reduced velocities. The system paper can contribute future construction actuators compensation turbines.
