The interaction of two dimensional incompressible viscous laminar flow with a vibrating airfoil is studied.The airfoil can rotate and oscillate in vertical direction. The numerical simulation consists of discretization and stabilization of the Navier-Stokes equations for high Reynolds numbers. In order to take the grid motion into account the Arbitrary Lagrangian-Eulerian formulation of the Navier-Stokes equations is used.

Tento článek se zabývá dvourozměrným nestlačitelným vazkým laminárním proudění okolo vibrujícího leteckého profilu, který se může otáčet okolo své elastické osy a posunovat ve vertikálním směru. Numerická simulace vyžaduje diskretizaci a stabilizaci Navierových-Stokesových rovnic pro vysoká Reynoldsova čísla. Vzhledem k deformaci sítě je využita Arbitrary Lagrangian-Eulerian formulace.
