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 α=9◦ and a chordbased
Reynolds number of Rec=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.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech
