    A Turbulent Flow Past a Cylinder

  • Original language description

    The paper deals with an incompressible flow past a circular cylinder in slightly turbulent flow regime. Numerical simulations was carried out by using unsteady Reynolds averaged Navier Stokes (URANS) approach with Spalart-Allmaras (SA) and detached-eddy-simulation (DES) turbulence models. Furthermore, experimental flow visualizations on hydrodynamic tank is presented as well. In the frame of this study parameters such as geometry, computational grid resolutions and mathematical models were considered. Results such as time averaged velocity fields and Reynolds shear stress etc. are compared with experimental data and good agreement was found.

    Turbulentní proudění za válcem

  • Czech description

    Tento článek se zabývá nestlačitelným prouděním za kruhovým válcem v mírně turbulentním režimu proudění. Numerická simulace byla uskutečněna použitím URANS přiblížení spolu s Spalart-Allmaras a DES modely turbulence. Dále je prezentována vizualizace proudění v hydrodynamické nádrži.
