Title:
An algebraic variational multiscale-multigrid-multifractal method (AVM^4) for large-eddy simulation of turbulent variable-density flow at low Mach number 
Abstract:
An algebraic variational multiscale-multigrid-multifractal method is proposed for large-eddy simulation of turbulent variable-density flow at low Mach number. In the multifractal subgrid-scale modeling approach, the subgrid-scale quantities are explicitly evaluated from a multifractal description of associated gradient fields. The multifractal subgrid-scale modeling approach is embedded into a residual-based form of the variational multiscale method. A particular feature of the proposed form of...    »
