Description	The subject of the paper is the numerical simulation of the interaction of two-dimensional incompressible viscous flow and a vibrating airfoil inserted in a channel (e.g. wind tunnel). A solid airfoil with two degrees of freedom can rotate around the elastic axis and oscillate in the vertical direction. The numerical simulation consists of the finite element solution of the Navier-Stokes equations coupled with the system of ordinary differential equations describing the airfoil motion. The time dependent computational domain and a moving grid are taken into account with the aid of the Arbitrary Lagrangian-Eulerian (ALE) formulation of the Navier-Stokes equations. High Reynolds numbers up to 10^6 require the application of a suitable stabilization of the finite element discretization. Numerical results are compared with an experiment.

(en) Článek se zabývá numerickou simulací interakce dvourozměrného vazkého nestlačitelného proudění v kanále a vibrujícího leteckého profilu. Práce se zabývá leteckým nosníkem se dvěma stupni volnosti. Numerická simulace se skládá z konečněprvkového řešení Navierových-Stokesových rovnic spojených se systémem nelineárních obyčejných diferenciálních rovnic popisujících pohyb nosníku. Problém je řešen na časově proměnné výpočtové oblasti pomocí Arbitrary Lagrangian-Eulerian (ALE) formulace. Vysoká Reynoldsova čísla až do 10^6 vyžadují použití vhodné metody stabilizace. Numerické výsledky jsou srovnány s experimentem. (cs)
