Abstract
The active flow control applied on the wing surface is an efficient method to prevent or delay flow separations and improve the overall aerodynamic performance. A numerical code based on RANS is used to simulate subsonic flow and steady blowing jet over the airfoil. This paper presents the grid study of an airfoil with different configurations of slat, flap positions and blowing momentum coefficients. The analysis is performed in terms of lift coefficient with the use of the Richardson extrapolation to estimate uncertainties due to mesh refinement and compared to experimental data. Results of drag coefficient are also analyzed according to each grid refinement. Finally, the influence of the proximity of far field to the airfoil is evaluated by the discrepancies of lift coefficient obtained from the simulations.
