Abstract
Large-eddy simulation (LES) using the dynamic Smagorinsky model (DSM) of incompressible turbulent flow in a lid-driven cubical cavity with lids moving in anti-parallel direction has been carried out at a Reynolds number of 12 000. The time history and power spectra of variables such as velocity components, turbulent production, turbulent kinetic energy have been reported for the maximum turbulent production zone. The distribution about the size of turbulent structure passing through the maximum turbulent production zone has been discussed. The shearing and the swirling structures are identified on statistically symmetric plane. The turbulent production and dissipation have been investigated at each impingement area in the averaged flow field. © 2013 Elsevier Ltd. All rights reserved.
