    Dual - Time Stepping Method Applied to a Numerical Solution of Unsteady Incompressible Flow with a Vibrating Profile

  • Original language description

    The paper presents numerical solution of two-dimensional incompressible flow in the interaction with a vibrating profile. The profile has two degrees of freedom. Mathematical model is represented either by the Euler equations in the case of invisicid flow or the Navier-Stokes equations in the case of viscous flow. Finite volume method is used as a discretization method. The dual-time stepping method is applied to unsteady simulations. This method provides a possibility to develop a time-accurate time-marching scheme for unsteady incompressible flows. Computational domain deformation due to the profile motion are treated using the Arbitrary Lagrangian-Eulerian method (ALE). Numerical schemes used for unsteady flow calculations are implemented a form satisfying the geometric conservation law (GCL).

    Užití duálního času k numerickému řešení nestacionárního nestlačitelného obtékání vibrujícího profilu

  • Czech description

    Článek se zabývá numerickým řešením 2D nestlačitelného proudění v interakci s vibrujícím profilem (dva stupně volnosti). Matematickým modelem jsou 2D Eulerovy rovnice či Navierovy-Stokesovy rovnice. Je užita metoda konečných objemů v kombinaci s užitím duálního času pro nestacionární proudění včetně užití ALE metody pro změnu sítě. Numerické schéma užité pro nestacionární proudění vyhovuje geometrickému zákonu zachování.
