In this paper we investigated the applicability of using synthetic jets to improve the efficiency of wind turbines. We used the NREL Phase VI rotor which is a stall regulated two bladed wind turbine with linear taper and nonlinear twist distribution over the blades and uses the S809 airfoil from root to tip. We validated our base flow (uncontrolled) results with the experimental tests that were performed in the NASA/AMES 80 ft. × 120 ft. wind tunnel. Synthetic jet is an active flow control device and was applied along the blade from root to tip at 0.1 chord location. The non-dimensionalized jet frequencies of = 1 and 0.5 and the blowing ratio of Vj/U∞ = 1 and 2 are used during the control cycle.
