Abstrakt

The study deals with numerical approximation of a 2D aeroelastic problem. A fully coupled formulation of flow over a freely vibrating airfoil with two degrees of freedom for rotation and translation is considered. The flow is described by the incompressible Navier-Stokes equations written in Arbitrary Lagrangian-Eulerian (ALE) form or by the Reynolds averaged Navier-Stokes system. The flow is solved by the stabilized finite element method. The developed method is verified by experimental data and the numerical results obtained for laminar and turbulent models are compared.
