On Approximation of Nonlinear Aeroelastic Problem with Three Degrees of Freedom

Popis výsledku v původním jazyce

In this paper, we consider the numerical approximation consisting of the finite element approximations of the Reynolds-averaged Navier-Stokes equations coupled with the system of nonlinear ordinary differential equations describing the airfoil motion. For the turbulence the k-omega turbulence model is used.The three degrees of freedom for the airfoil are considered. Both the geometrical and structural nonlinearities are taken into account. An attention is paid to the efficiency of the solution of the space-time discretized nonlinear flow problem. The multigrid solution strategy is discussed. The motion of the computational domainis treated with the aid of the arbitrary Lagrangian-Eulerian (ALE) formulation. The dominating convection is stabilized withthe aid of the residual based stabilization. The numerical solution is sought on adaptivily refined meshes. The Oseen iterative process is used and the multigrid method is used for the solution of the linear system of equations. The appli
