#include <incompressibleLESModels/Smagorinsky2.H>


Detailed Description

The Isochoric Smagorinsky Model for incompressible flows.

Algebraic eddy viscosity SGS model founded on the assumption that local equilibrium prevails, hence

B = 2/3*k*I - 2*nuSgs*dev(D) - 2*cD2*delta*(D.dev(D));
Beff = 2/3*k*I - 2*nuEff*dev(D) - 2*cD2*delta*(D.dev(D));

where

D = symm(grad(U));
k = cI*delta^2*||D||^2
nuSgs = ck*sqrt(k)*delta
nuEff = nuSgs + nu

tmp< fvVectorMatrix > divDevBeff ( volVectorField &   U  ) const [virtual]

Returns div(B).

This is the additional term due to the filtering of the NSE.
