Active flow control, for fixed wings, using synthetic jets

Flow separation is a challenging and undesired phenomenon in the aerodynamics. In the past decades, various approaches for the reduction of flow separation has been sought. Therefore, the use of synthetic jets has been explored as means of the reduction of flow separation. The present research concerns the effect of inclination angle, of the injector, on the flow separation of NACA0012 airfoil. The computational studies are performed using the large-eddy simulation (LES) approach. The effect of the blowing ratio is also subject of investigation in the present study. The study shows that both the inclination angle and blowing ratio affect the flow separation and contribute significantly to the reduction of the flow separation.
