Description	The subject of this paper is the numerical simulation of the interaction between two-dimensional incompressible viscous flow and a vibrating airfoil. A solid elastically supported airfoil with two degrees of freedom, which can rotate around the elastic axis and oscillate in the vertical direction, is considered. The numerical simulation consists of the stabilized finite element solution of the Reynolds averaged Navier-Stokes equations with algebraic models of turbulence, coupled with the system of ordinary differential equations describing the airfoil motion. Since the computational domain is time dependent and the grid is moving, the Arbitrary Lagrangian-Eulerian (ALE) method is used. The developed method was applied to the simulation of flow-induced airfoil vibrations.

(en) Článek se zabývá numerickou simulací interakce dvourozměrného nestlačitelného proudění a vibrujícího profilu se dvěma stupni volnosti, otáčení kolem elastické osy a vertikální pohyb. Numerická simulace se skládá z aplikace stabilizované metody konečných prvků na Reynolsovy středované rovnice, doplněné algebraickým modelem turbulence a spojené se systémem obyčejných diferenciálních rovnic. Pohyb sítě je uvážen pomocí tzv. Arbitrary Lagrangian-Eulerian (ALE) metody. (cs)
