Description
  • The subject of this paper is the numerical simulation of the interaction of two-dimensional incompressible viscous flow and a vibrating airfoil. A solid airfoil with two degrees of freedom can rotate around an elastic axis and oscillate in the vertical direction. The numerical simulation consists of the finite element solution of the Navier-Stokes equations coupled with a 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 formulation of the Navier-Stokes equations. High Reynolds numbers require the application of a suitable stabilization of the finite element discretization. Numerical tests prove that the developed method is sufficiently accurate and robust. The results are compared with experiments.

  • Předmětem článku je numerická simulace interakce 2D nestlačitelného vazkého proudění a kmitajícího profilu. Je uvažován pevný profil se dvěma stupni volnosti. Problém je numericky simulován prostřednictvím přibližného řešení Navierových-Stokesových rovnic metodou konečných prvků a spojen se systémem obyčejných diferenciálních rovnic popisujících pohyb profilu. Časově závislá oblast je vzata do úvahy pomocí Arbitrary Lagrangian-Eulerian metody. Získané výsledky jsou srovnány s experimentem. (cs)
