TitleThe residual-based variational multiscale formulation for the large eddy simulation of compressible flows
Year2012
JournalComputer Methods in Applied Mechanics and Engineering
AbstractThe residual-based variational multiscale formulation is applied to develop a large eddy simulation (LES) model for compressible flows. In addition, a mixed model, in which a deviatoric Smagorinsky subgrid stress term is added to the RBVM terms to better model the Reynolds stresses is proposed. These models, along with the dynamic Smagorinsky-Yoshizawa-eddy diffusivity model are tested in predicting the decay of homogenous turbulence. For most relevant measures, it is observed that the RBVM models are more accurate than the dynamic Smagorinsky-type model.
