Omidyeganeh, Mohammad; Abedi, Jalal Numerical simulation of the wind flow around a cube. (English) Zbl 1278.76071 Adv. Appl. Fluid Mech. 13, No. 2, 99-125 (2013). Summary: A new finite volume code is developed to solve the Navier-Stokes and continuity equations using large eddy simulation (LES) for the turbulent flow. The finite volume formulation is applied on the staggered grid arrangement for a structured mesh system. Smagorinsky-Lilly sub-grid scale (SGS) model was used which can be substituted with other models easily. The discretization scheme for all terms except the convection terms, which adopts a TVD scheme, was the central difference scheme. The PISO algorithm had found to be faster than the SIMPLE algorithm for all cases and problems. Larger sub-grid scale constant elevates the stagnation point in front face of the cube and also damps the turbulence behind the obstacle. Moreover, the mostly needed modifications had been proposed and estimated.
