title = "Separation control from the flap of a high-lift airfoil using DBD plasma actuators",
abstract = "Control of separation from the deflected flap of a high-lift airfoil is explored using two asymmetric dielectric barrier discharge (DBD) plasma actuators straddling the flap shoulder for Reynolds numbers of 240,000 and 410,000. Actuators are found to be most effective when operated in an unsteady fashion at the natural oscillation frequency of the trailing edge flow field. The use of two actuators shows a significant improvement over one actuator by further decreasing the size of the time-averaged separation bubble on the flap while increasing the pressure fluctuations and velocity fluctuations over the flap and in the wake. Results indicate that the primary mechanism for reducing separation in this configuration is an enhancement of the natural vortex shedding that encourages momentum transfer between the freestream and separated region.",
