Abstract

The effects of a pulse actuation on the Lagrangian Coherent Structures (LCS) in the separated flow over a NACA 65(1)-412 airfoil at low Reynolds number is investigated. A computational parametric study is performed on the effect of location over the suction side of the airfoil. An increased local separation angle leads to flow reattachment of the Lagrangian material line. Reattachment is accompanied by an increase in the lift and reduction in drag. The optimal pulse actuation is near the Lagrangian separation point.
