In this study, turbulent flow around a tube bundle in non-orthogonal grid is simulated using the Large Eddy Simulation (LES) technique and parallelization of fully coupled Navier – Stokes (NS) equations. To model the small eddies, the Smagorinsky and a mixed model was used. This model represents the effect of dissipation and the grid-scale and subgrid-scale interactions. The fully coupled NS eq...

Algebraic explicit wall models covering the entire inner region of turbulent boundary layer are proposed to reduce computational effort for large eddy simulation wall-bounded flows. The formulas given in closed forms with either logarithmic- or power-function-based laws wall, allowing straightforward evaluation friction velocity on near grids independent their locations layer. performance is de...
