Commutator-errors in large-eddy simulation
Bernard J. Geurts, Darryl D. Holm
A new formulation is derived for the commutator-errors in large-eddy simulation of incompressible flow. These commutator-errors arise from the application of non-uniform filters to…

Buoyant turbulent mixing in shear layers
Bernard J. Geurts
Buoyancy effects in unstably stratified mixing layers express themselves through gravity currents of heavy fluid which propagate in an ambient lighter fluid. These currents are enc…

Alpha-modeling strategy for LES of turbulent mixing
Bernard J. Geurts, Darryl D. Holm
The -modeling strategy is followed to derive a new subgrid parameterization of the turbulent stress tensor in large-eddy simulation (LES). The LES- modeling yields an explici…
