Diierent dynamic subgrid scale models, viz. the dynamic model of Germano et al. are evaluated by means of a priori tests. Direct numerical simulation data for fully-developed turbulent and transitional incompressible ows are used. Low correlation is obtained between exact and modeled subgrid scale stresses with the DSM. Conversely, good agreement is found for both the DMM and the DTM, since tho...

A Family of Dynamic Models for Large-eddy Simulation

Since its rst application, the dynamic procedure has been recognized as an eeec-tive means to compute rather than prescribe the unknown coeecients that appear in a subgrid-scale model for Large-Eddy Simulation (LES). The dynamic procedure (Germano et al. 1991; Ghosal et al. 1995) is usually used to determine the non-dimensional coeecient in the Smagorinsky (1963) model. In reality the procedure...
