By coupling a two-degree-of-freedom structural model with an in-house CFD code, large-eddy simulations were performed for a free-mounted NACA0012 airfoil at low Reynolds numbers. As observed in experiments, the simulations confirmed the limit-cycle oscillations resulting from the unsteadiness of the laminar boundary layer separation and its delayed recovery.
