Detailed Description

One Equation Eddy Viscosity Model for incompressible flows.

Eddy viscosity SGS model using a modeled balance equation to simulate the behaviour of k, hence,

d/dt(rho*k) + div(rho*U*k) - div(muEff*grad(k))
=
-rho*D:B - ce*rho*k^3/2/delta

and

B = 2/3*k*I - 2*nuSgs*dev(D)

where

D = symm(grad(U));
muSgs = ck*rho*sqrt(k)*delta
