Abstract
The mixednonlinear Kosovic, Leray and LANSalpha subgrid scale models are contrasted with linear Smagorinsky and Yoshizawa largeeddy simulations for a Re = 4000 plane jet simulation. Comparisons are made with direct numerical simulation data and reliable measurements. Global properties of the jet such as the spreading and centerline velocity decay rates are investigated. The meanflow and turbulence parameters in the selfsimilar region are also studied. Mixed models developed for boundary layers compare well with the benchmark jet data and the linear model predictions. Differences between the models are minor and none showed any clear advantage in all the data comparisons. (c) 2007 Elsevier Ltd. All rights reserved.
