Název v původním jazyce

Application of Finite Element Method in Aeroelasticity

Popis výsledku v původním jazyce

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, which can rotate around the elastic axis and oscillate in the vertical direction, is considered. The numerical simulation consists of the finite element approximation of the Navier-Stokes equations coupled with the system of ordinary differential equations describing the airfoil motion. A sufficiently accurate and robust method is developed, which is applied to the case of flow induced airfoil vibrations. The computational results of aeroelastic calculations are compared with the NASTRAN code solution of linear approximation as well as with the numerical simulations of Reynolds Averaged Navier-Stokes equations with the Spallart-Almaras one equation turbulence model.
