SUMMARY The turbulent flow past a circular cylinder (Re=3900) was computed by large eddy simulation (LES). objective not to investigate the physical phenomena of this in detail but study numerical and modeling aspects which influence quality LES solutions. Concerning method, most important component is discretization non-linear convective fluxes. Five different schemes were investigated. Also, grid resolutions examined. Two play an role on side, namely near-wall model subgrid scale model....
This paper is concerned with the behavior of flows over a backward-facing step geometry for various expansion ratios H/h=1.9423, 2.5 and 3.0. A literature survey was carried out it found that flow shows strong two-dimensional behavior, on plane symmetry, Reynolds numbers ReD=ρUbD/μ below approximately 400 (Ub=bulk velocity D=hydraulic diameter). In this number range, predictions were to provide information general integral properties flows, mean distributions streamlines. Information...
A two-dimensional numerical study on the laminar flow past a circular cylinder rotating with constant angular velocity was carried out. The objectives were to obtain consistent set of data for drag and lift coefficients wide range rotation rates not available in literature deeper insight into field vortex development behind cylinder. First, Reynolds numbers (0.01⩽Re⩽45) (0⩽α⩽6) considered steady regime, where α is circumferential at surface normalized by free-stream velocity. Furthermore,...
Abstract The separated turbulent flow past an inclined flat plate with sharp leading and trailing edges was computed based on three different simulation approaches for a reynolds number Re c = 20000 high angle of attack α=18°. techniques applied were the Reynolds‐averaged Navier–Stokes (RANS) equations combined one‐equation Spalart–Allmaras turbulence model, large‐eddy (LES) algebraic eddy‐viscosity hybrid approach known as detached‐eddy (DES) applying slightly modified model in entire...
The internal flow over a backward-facing step in the transitional regime ( Re D = 6000) was studied based on direct numerical simulations. predictions were carried out with help of finite-volume Navier–Stokes solver equipped co-visualization facility which allows one to investigate dynamics at high temporal resolution. First, grid-induced oscillations precluded by careful grid design. Second, strong influence velocity profile approaching and outlined. main objective, however, provide...
