Description
  • The work deals with a numerical solution of two-dimensional inviscid incompressible flow over a profile NACA 0012 with two degrees of freedom. The profile can rotate around an elastic axis and oscillate in the vertical direction. The finite volume method in a form of a cell-centered scheme at quadrilateral C-mesh is considered. The mathematical model of the fluid flow is represented by a modified system of unsteady Euler equations. The motion of the profile is described by a system of two ordinary differential equations. The numerical simulation of flow induced vibrations of the profile consists in a coupling of the two systems of equations. An arbitrary Lagrangian-Eulerian method is employed to solve unsteady flows on a moving grid.

  • Práce se zabývá numerickým řešením dvourozměrného nevazkého nestlačitelného proudění kolem profilu NACA 0012 se dvěma stupni volnosti. Profil se může otáčet kolem elastické osy a kmitat ve vertikálním směru. Je uvažována metoda konečných objemů ve formě centrálního schématu na čtyřúhelníkové síti typu C. Matematický model proudění tekutiny je reprezentován modifikovaným systémem nestacionárních Eulerových rovnic. Pohyb profilu je popsán systémem dvou obyčejných diferenciálních rovnic druhého řádu. Numerické řešení vybuzeného kmitání profilu spočívá v propojení dvou výše zmíněných systémů rovnic. Arbitrary Lagrangian-Eulerian metoda je použita pro řešení nestacionárního proudění na pohybující se síti. (cs)
