Class
    Foam::liftModels::TomiyamaLift

Description
    Lift model of Tomiyama et al.

    Reference:
    \verbatim
        "Transverse migration of single bubbles in simple shear flows"
        Tomiyama, A., Tamai, H., Zun, I., Hosokawa, S.,
        Chemical Engineering Science
        Volume 57, Issue 11, June 2002, pp. 1849-1858
    \endverbatim

    The coefficient for pow3(EoH) proposed by Tomiyama (2002) has been modified
    to make the model continuous at EoH = 10.7 while maintaining the
    lift coefficient proposed by Tomiyama (2002) when EoH >= 10.7.
