Description
    The Smagorinsky SGS model including bubble-generated turbulence
 
    Reference:
    \verbatim
        Zhang, D., Deen, N. G., & Kuipers, J. A. M. (2006).
        Numerical simulation of the dynamic flow behavior in a bubble column:
        a study of closures for turbulence and interface forces.
        Chemical Engineering Science, 61(23), 7593-7608.
    \endverbatim
 
    The default model coefficients are
    \verbatim
        SmagorinskyZhangCoeffs
        {
            Ck              0.094;
