Class
    Foam::dragModels::Beetstra

Description
    Drag model of Beetstra et al. for monodisperse gas-particle flows obtained
    with direct numerical simulations with the Lattice-Boltzmann method and
    accounting for the effect of particle ensembles.

    Reference:
    \verbatim
        Beetstra, R., van der Hoef, M. A., & Kuipers, J. a. M. (2007).
        Drag force of intermediate Reynolds number flow past mono- and
        bidisperse arrays of spheres.
        AIChE Journal, 53(2), 489–501.
