We perform two-dimensional simulations of unsteady flow separation around a NACA0015 airfoil. The effects of Reynolds number and the angle of attack of the airfoil were studied. With the increase in the angles of attack and the Reynolds number, it reveals a route of the transition in the wake of NACA0015 foil from steady to chaotic flow. We find that the flow transits from steady flow to a chaotic state by a sequence of successive period-doubling bifurcations. Our results provide physical insight into the wake transition of an airfoil from steady to chaotic flow.
