CFD simulations of the AFC effect are usually highly time consuming and require extensive computational resources and effort. These aspects almost exclude the simulation of the actuator arrays and the application of AFC during the design process. This study is focused on the development of simplified surface boundary condition of the actuator's effect on the flow-field and to enable significant reduction of the computational resources. The simplified boundary condition is based on the high-fidelity unsteady CFD simulations of the internal flowfield of the Suction and Oscillatory Blowing (SaOB) actuator in still air condition and takes into account the time dependent flowfield variables at the actuator's exit. The developed boundary condition is applied to a dataset with flow control applied to a low-speed airfoil in cross flow to verify its effect on circulation.
