Stabilized Finite Element Approximations of Flow over a Self - Oscillating Airfoil
Original language description
The paper presents the comparison of numerical solution of a 2D aeroelastic problem and experimental results. For the numerical approximation the coupled formulation of a turbulent flow over an oscillating solid airfoil is considered. The flow is modelled by the incompressible Reynolds averaged Navier-Stokes (RANS) equations rewritten in Arbitrary Lagrangian-Eulerian (ALE) form and discretized by the stabilized finite element method (FEM). The numerical results are compared with the results of optical measurements of flow field around an elastically supported vibrating double circular arc (DCA) 18% profile. The measurements were performed above the critical airflow velocity for loss of the system stability by flutter. The numerical results for the timedependent pressure distribution on the fluttering airfoil are presented.
