29 The Isochoric Smagorinsky Model for incompressible flows
31 Algebraic eddy viscosity SGS model founded on the assumption that
32 local equilibrium prevails, hence
34 B = 2/3*k*I - 2*nuSgs*dev(D) - 2*cD2*delta*(D.dev(D));
35 Beff = 2/3*k*I - 2*nuEff*dev(D) - 2*cD2*delta*(D.dev(D));
40 k = cI*delta^2*||D||^2
41 nuSgs = ck*sqrt(k)*delta
