The incompressible turbulent flow over a freely vibrating airfoil, with two degrees of freedom for rotation and translation with large vibration amplitudes, is described by the Reynolds averaged NavierStokes (RANS) equations written in Arbitrary Lagrangian-Eulerian (ALE) form. The Spalart-Allmaras turbulence model is used. The flow is solved by the stabilized finite element method. The numerical results are compared with the optical measurements of flow field around a fluttering double circular arc (DCA) 18% profile elastically supported in a subsonic wind tunnel. The interferometry method was used for airflow visualization in different phases of the profile motion. The numerical results for the pressure on the profile surface are in good agreement with the measurement.
