Local flow topology and velocity gradient invariants in compressible turbulent mixing layer
(Cambridge University Press, 2015-06-04)
The local flow topology is studied using the invariants of the velocity gradient tensor in compressible turbulent mixing layer via direct numerical simulation (DNS) data. The topological and dissipating behaviours of the ...
A priori assessment of the subgrid scale viscous/scalar dissipation closures in compressible turbulence
(Taylor & Francis, 2013-11-18)
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 ...
