isothermalFilm/fvModels/filmCloudTransfer/ejectionModels: New film->cloud transfer sub-models

Browse Source 
The filmCloudTransfer fvModel now supports an optional ejection model which
provides transfer of film to cloud by dripping from an inverted surface or
curvature separation:

Class
    Foam::filmEjectionModels::dripping

Description
    Dripping film to cloud ejection transfer model

    On an inverted surface if the film thickness is sufficient to generate a
    valid parcel the equivalent mass is removed from the film and transfered to
    the cloud as a parcel containing droplets with a diameter obtained from
    the specified parcelDistribution.

Usage
    Example usage:
    \verbatim
    filmCloudTransfer
    {
        type    filmCloudTransfer;

        libs    ("libfilmCloudTransfer.so");

        ejection
        {
            model   dripping;

            deltaStable 5e-4;

            minParticlesPerParcel 10;

            parcelDistribution
            {
                type            RosinRammler;
                Q               0;
                min             1e-3;
                max             2e-3;
                d               7.5e-05;
                n               0.5;
            }
        }
    }
    \endverbatim

Class
    Foam::filmEjectionModels::BrunDripping

Description
    Brun dripping film to cloud ejection transfer model

    If the film thickness exceeds the critical value needed to generate one or
    more drops, the equivalent mass is removed from the film.  The critical film
    thickness is calculated from the Rayleigh-Taylor stability analysis of film
    flow on an inclined plane by Brun et.al.

    Reference:
    \verbatim
        Brun, P. T., Damiano, A., Rieu, P., Balestra, G., & Gallaire, F. (2015).
        Rayleigh-Taylor instability under an inclined plane.
        Physics of Fluids (1994-present), 27(8), 084107.
    \endverbatim

    The diameter of the drops formed are obtained from the local capillary
    length multiplied by the \c dCoeff coefficient which defaults to 3.3.

    Reference:
    \verbatim
        Lefebvre, A. (1988).
        Atomisation and sprays
        (Vol. 1040, No. 2756). CRC press.
    \endverbatim

Usage
    Example usage:
    \verbatim
    filmCloudTransfer
    {
        type    filmCloudTransfer;

        libs    ("libfilmCloudTransfer.so");

        ejection
        {
            model   BrunDripping;

            deltaStable 5e-4;
        }
    }
    \endverbatim

Class
    Foam::filmEjectionModels::curvatureSeparation

Description
    Curvature induced separation film to cloud ejection transfer model

    Assesses film curvature via the mesh geometry and calculates a force
    balance of the form:

        F_sum = F_inertial + F_body + F_surface_tension

    If F_sum < 0, the film separates and is transferred to the cloud
    if F_sum >= 0 the film remains attached.

    Reference:
    \verbatim
        Owen, I., & Ryley, D. J. (1985).
        The flow of thin liquid films around corners.
        International journal of multiphase flow, 11(1), 51-62.
    \endverbatim

Usage
    Example usage:
    \verbatim
    filmCloudTransfer
    {
        type    filmCloudTransfer;

        libs    ("libfilmCloudTransfer.so");

        ejection
        {
            model   curvatureSeparation;

            deltaStable 5e-4;
        }
    }
    \endverbatim

The new tutorials/modules/multiRegion/film/cylinderDripping tutorial case
demonstrates a film dripping into the cloud.  The standard cylinder case is
turned upside-down (by changing the orientation of gravity) with an initial
0.2mm film of water over the surface which drips when the thickness is greater
than 0.5mm.  Settings for all three ejection models are provided in the
constant/film/fvModels dictionary with the standard dripping model selected.
