Abstract

The turbulent flow fieldgeneratedin an unbaffledstirredtank by a Rushton turbine was computedby large-eddy simulation (LES). TheSmagorinsky model was used to model the unresolved, or sub-grid, scales. A general purpose CFD code was appropriately modified inorder to allow the computation of the sub-gridviscosity andto perform statistics on the computedresults. The numerical predictions were comparedwith the literature results for comparable configurations andwith experimental data obtainedusing particle image velocimetry.A very goodagreement was foundas regards both time-averagedresolv edfield s andturb ulence quantities. 2004 Elsevier Ltd.
