Class
    Foam::populationBalance::coalescenceModels::AdachiStuartFokkink

Description
    Model describing aggregation of solid particles in turbulent flows.
    Applicable when particles are smaller than the Kolmogorov length scale.
    The coalescence rate is calculated by

    \f[
        \frac{4}{3}\left(\frac{3\pi}{10}\right)^{0.5}
        \left(\frac{\epsilon}{\nu}\right)^{0.5}(d_i+d_j)^3
    \f]

    where

    \vartable
        d_i      | Diameter of particle i [m]
        d_j      | Diameter of particle j [m]
        \nu      | Kinematic viscosity of continuous phase [m2/s]
        \epsilon | Continuous phase turbulent dissipation rate [m2/s3]
    \endtable
