Abstract
Recently, a new sub-grid-scale model pertaining to large eddy simulation methodology, namely shear improved-Smagorinsky model has been proposed. The model takes into account the mean shear arising due to anisotropy of the flow. In the present study, the model has been tested successfully on shear driven cavity flow to see its strength in predicting the complex flow features associated with separation or detached shear layer and analyze the associated numerical difficulties. The results have been compared with experimental data and findings from commonly used LES model. The model agrees well with the experimental counterpart and comparable with those due to other LES model.
