Abstract
Large-eddy simulation (LES) of the incompressible turbulent flow in a two-sided lid-driven cubical cavity with lids moving in anti-parallel direction has been carried out at a Reynolds number of 12,000. The transient behaviour of the corner eddies have been discussed on the statistically symmetric plane. Time averaged solutions have been obtained by performing a long-lasting simulations using multiprocessing. The presence of four more eddies except the well known two corner eddies have been found in the transverse plane of the main core flow direction. The extent of the main average recirculating flow in the central core region in the x–z and y–z plane has been reported. The specific features of turbulent flow inside the cavity such as inhomogeneity of turbulence, small-scales localisation, second order turbulent statistics, cross-correlation of vorticity component and coherent structure of flow have been investigated.
