ABSTRAKT
A new two-equations subgrid-scale model is proposed for large eddy simulations using coarse grids. The characteristic subgrid-scale of turbulence is no longer given by the step size but is obtained by a dissipation equation. Thus, the model is better suited for non-equilibrium turbulence. The application to turbulence submitted to periodic forcing in pulsed channel flow shows some potentials of the method.
