This work investigates the three-dimensional effects of a dielectric barrier discharge actuator as a stall recovery device. The actuator is installed on a NACA0015 airfoil with a 930 mm span and a 300 mm chord and the exposed electrode has periodic triangular tips specifically designed for the case under study. It was tested at progressively increasing velocities, up to 35 m/s corresponding to a Reynolds number of 7×105. The PIV technique has been used to characterize the flow morphology along the model span, identifying the flow region mainly sensitive to the plasma effect and suggesting possible design improvements to achieve a better efficiency.

Abstract
This work investigates the three-dimensional effects of a dielectric barrier discharge actuator as a stall recovery device. The actuator is installed on a NACA0015 airfoil with a 930 mm span and a 300 mm chord and the exposed electrode has periodic triangular tips specifically designed for the case under study. It was tested at progressively increasing velocities, up to 35 m/s corresponding to a Reynolds number of 7×105. The PIV technique has been used to characterize the flow morphology along the model span, identifying the flow region mainly sensitive to the plasma effect and suggesting possible design improvements to achieve a better efficiency.| File | Dimensione | Formato | |
