In this article we are concerned with the numerical solution of an aeroelastic problem of two dimensional viscous incompressible flow around an airfoil with three degrees of freedom in a wind tunnel the airfoil is represented by a solid body, which can perform vertical and torsional vibrations and its flap can rotate with respect to the airfoil. Model of the flow is formed by two-dimensional Navier-Stokes equations and the continuity equation. Stabilized finite element method is used for obtaining a numerical solution. Due to the motion of the airfoil the computational domain is time-dependent.
