Clipping refers to adding 1 line of code A ⇐ min{A,B} to force the variable A to stay below a present bound B. Phenomenological clipping also occurs in turbulence models to correct for over dissipation caused by the action of eddy viscosity terms in regions of small scales. Herein we analyze eddy viscosity model energy dissipation rates with 2 phenomenological clipping strategies. Since the true Reynolds stresses are O(d) (d = wall normal distance) in the near wall region, the first is to force… Expand

Abstract Turbulence models, such as the Smagorinsky model herein, are used to represent the energy lost from resolved to under-resolved scales due to the energy cascade (i.e. non-linearity). AnalyticExpand
On the Prandtl-Kolmogorov 1-equation model of turbulence
TLDR
It is proved an estimate of total (viscous plus modelled turbulent) energy dissipation in general eddy viscosity models for shear flows and shows that the ratio of the near wall average Viscosity to the effective global viscosities is the key parameter. Expand

TLDR
It is proven that the model's time averaged energy dissipation rate satisfies the same upper bound as for the NSE plus one additional term that vanishes uniformly in the Reynolds number as the Smagorinsky length scale decreases. Expand
