An appraisal is made of several subgrid scale (SGS) viscous/scalar dissipation closures via a priori analysis of direct numerical simulation data in a temporally evolving compressible mixing layer. The effects of the filter ...

Direct numerical simulations (DNS) of temporally evolving shear layers have been performed to investigate the mechanisms associated with the entrainment process and to study the dynamics and the kinematics of turbulent/n ...
