description This is the first part of a two part paper on flow around vibrating wind turbine airfoils. In this part 1, the unsteady, incompressible, viscous and laminar flow over a forced oscillating airfoil is computed using a method based on a commercial Computational Fluid Dynamics (CFD) code. Beforehand, the Navier-Stokes equations are solved for the unsteady flow around a NACA 0012 airfoil at a fixed 20 deg incidence and the low Reynolds numbers of 103 and 104 to check the reliability of the CFD computations. Then the flow around a pitching airfoil is simulated for prescribed values of the reduced frequency. The Navier-Stokes equations are expressed in ALE formulation and solved with moving mesh. The effects of the discretization scheme and the moving mesh technique are investigated. The hysteresis loops of the dynamic stall phenomenon are highlighted.
