Numerical Simulation of Flow Induced Airfoil Vibrationswith Large Amplitudes

Popis výsledku v původním jazyce

The subject of this contribution is the numerical simulation of the interaction oftwo-dimensional incompressible viscous flow and a vibrating airfoil. A solid airfoilwith two degrees of freedom, which can rotate around the elastic axis and oscillatein the vertical direction, is considered. The numerical simulation consists of thefinite volume solution of the Navier-Stokes equations, coupled with the system ofordinary differential equations describing the airfoil motion. The time-dependentcomputational domain and a moving grid are taken into account with the aid of thearbitrary Lagrangian–Eulerian (ALE) formulation of the Navier–Stokes equations.Special attention is paid to the time discretization and the solution of the non-linear discrete problem on each time level is performed. Numerical solutions areobtained with free accessible open-source code OpenFOAM. The computational re-sults are compared with known aerodynamical data and with results of aeroelasticcalculations obtained by a linear approximation.
