Title:
Residual-based variational multiscale methods for laminar, transitional and turbulent variable-density flow at low Mach number 
Abstract:
In the present study, residual-based variational multiscale methods are developed for and applied to variable-density flow at low Mach number. In particular, two different formulations are considered in this study: a standard stabilized formulation featuring SUPG/PSG/grad-div terms and a complete residual-based variational multiscale formulation additionally containing cross- and Reynolds-stress terms as well as subgrid-scale velocity terms in the energy-conservation equation. The proposed metho...    »
