Synthetic jet actuators provide a novel scheme for controlling flows because they require only electrical power and not plumbing to generate a control jet. Applications for this type of actuator include separation control, thrust vectoring, enhanced mixing, and passive maneuvering. However, better understanding of the interactions between these devices and the external flow must be attained before they can be efficiently implemented on a flight vehicle. This work focuses on an approach for modeling these actuators and applying them to an airfoil to attain increased lift. A boundary condition that can be incorporated into a RANS CFD code is developed and validated for a number of different cases, including the interaction between two jets and flow over an airfoil.
