The present research investigates the results of DES simulation of a finite span wing equipped with synthetic jet actuator (SJA), in order to study the influence of the jet exit location on the aerodynamic forces and streamlines. The wing airfoil is S809 with the chord length 400 mm, which is stretched 200 mm and rotated to create the angle of attack of 25℃. The momentum coefficient for the SJA is considered to be 4.5×10<SUP>- 3</SUP>. The results of the jet exit locations 0.25, 0.35 and 0.45 are analysed . It is observed that for all cases the SJA affects the aerodynamic behavior of wing and the flow patterns and aerodynamic forces on the wing are sensitively dependent on the jet exit location. When the jet exit location is at x/c=0.25, the SJA presents an effective role; however, for the cases in which the jet exit is located at x/c=0.35 or 0.45, the SJA effects become weaker and the range of results of are very close to each other.
