Numerical Modeling of turbulent flow in lid driven cavity using large eddy simulation

In this paper، Smagorinsky subgrid scale model is developed to numerically simulate Lid- driven cavity problem in laminar and turbulent conditions. Staggered and collocated grids were used in modeling. Horizontal and vertical velocity profiles in the cavity center for different Reynolds numbers were estimated and compared with Ghia results. The achievements showed that the results are improved using staggered grids and Smagorinsky coefficient in a range of 0. 5 to 0. 7.
