Keywords: airfoil, stall, Detached Eddy Simulation

The Detached-Eddy Simulation (DES) method is applied to calculate pre- and post-stall aerodynamic characteristics of thin airfoil stall. A discrepancy between numerical and experimental data is observed near the stall regime. The reason of this discrepancy and also possible ways for improvement of the numerical model are discussed.
