A simple subgrid eddy-viscosity model has been proposed. It has the advantage that it automatically reduces in laminar, transitional and near-wall regions, and it is therefore an attractive alternative for the classic Smagorinsky model. Examples of implementation: a Fortran module and a user-defined function for Fluent.
