One Equation Eddy Viscosity Model ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Eddy viscosity SGS model using a modeled balance equation to simulate the behaviour of k, hence,
d/dt(k) + div(U*k) - div(nuSgs*grad(k)) = -rho*B*L - ce*rho*k^3/2/delta
and
B = 2/3*k*I - 2*nuEff*dev(D)
where
D = symm(grad(U)); muSgs = rho*ck*sqrt(k)*delta muEff = muSgs + mu
