Titel:
An algebraic variational multiscale-multigrid method for large-eddy simulation of turbulent variable-density flow at low Mach number 
Abstract:
An algebraic variational multiscale-multigrid method is proposed for large-eddy simulation of turbulent variabledensity flow at low Mach number. Scale-separating operators generated by level-transfer operators from plain aggregration algebraic multigrid methods enable the application of modeling terms to selected scale groups (here, the smaller of the resolved scales) in a purely algebraic way. Thus, for scale separation, no additional discretization besides the basic one is required, in contras...    »
