Description
    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(nuEff*grad(k))
        =
        -B*L - ce*k^3/2/delta

    and

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

    where

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