Numerical simulation of interaction of a vibrating airfoil with turbulent flax

The report deals with numerical simulations of 2D viscous incompressible flow around a rotationaly vibrating profile. The flow is described by continuity and Navier-Stokes equations. Solution of the partial differential equations is based on finite element method. Because the Reynolds numbers higher than 10 000 are considered the solution is stabilized by SUPG method. Alge-braic turbulence model is taken into account and for simulations of the flow on moving grids the ALE method is used. the method was applied on harmonie vibrations of the profil NACA 0012 and the results are in good agreement with the experimental data obtained in ARTI
