This study investigates the effect of the variation of the active control application distance on the frequency response of a Batchelor vortex. The theoretical base flow pertains to the experimental configuration of a wing model with a NACA0012 airfoil at an angle of attack of alpha=9º and a chord-based Reynolds number of Re_c=40000. The injection was implemented using punctual and annular jet configurations. The findings of this research will serve as a basis for the optimization of the experimental parameters that characterize potential candidates for active control.
