Description
  • Článek se zabývá numerickým řešením interakce 2D proudění neviskozní nestlačitelné tekutiny s vibrujícím profilem o 2 stupních volnosti. Profil může oscilovat kolem elastické osy a ve vertikálním směru. Proudění je reprezentováno Eulerovými rovnicemi a numerické řešení metodou konečných objemů je aplikováno na strukturované obdélníkové C-síti. K řešení jsou použity metody umělé stlačitelnosti a duálního času. Pohyb profilu je popsán dvěmi obyčejnými diferenciálními rovnicemi a řešeny metodou Runge-Kutta 4. řádu. Deformace výpočetní oblasti vlivem pohybu profilu jsou respektovány s použitím ALE metody. Numerické simulace vibrací generovaných proudem vzduchu jsou prezentovány pro profil NACA 0012 a obě výpočetní metody jsou porovnány. (cs)
  • The work deals with a numerical solution of the interaction of 2D inviscid incompressible flow and a vibrating profile with two degrees of freedom. The profile can oscillate around an elastic axis and in the vertical direction. The airflow is represented by the Euler equations. Numerical schemes in the form of finite volume method are applied on a structured quadrilateral C-mesh. Two strategies, an artificial compressibility and a dual-time stepping method, are employed for numerical solution. The motion of the profile is described by two ordinary differential equations and solved using four-order Runge-Kutta method. Deformations of the computational domain due to the profile motion are treated using the Arbitrary Lagrangian-Eulerian method. Numerical simulations of flow-induced vibrations are performed for the profile NACA 0012 the two numerical strategies are compared.
