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(k) + div(U*k) - div(nuEff*grad(k)) = -B*L - ce*k^3/2/delta and B = 2/3*k*I - 2*nuSgs*dev(D) Beff = 2/3*k*I - 2*nuEff*dev(D) where D = symm(grad(U)); nuSgs = ck*sqrt(k)*delta nuEff = nuSgs + nu
