Class
    Foam::distributionModels::massRosinRammler

Description
    Mass-based Rosin-Rammler distributionModel.

    Corrected form of the Rosin-Rammler distribution taking into account the
    varying number of particles per parcel for for fixed-mass parcels.  This
    distribution should be used when
