Class
    Foam::wallBoilingModels::filmBoilingModels::Bromley

Description
    A correlation for boiling film modelling
    based on Bromley (1950) for boiling flows.

    Reference:
    \verbatim
        Bromley, L. A. (1950).
        Heat transfer in stable film boiling.
        Chemical Engineering Progress, 46, 221-227.
    \endverbatim

Usage
    Example of the model specification:
    \verbatim
    filmBoilingModel
    {
        // Mandatory entries
        type            Bromley;
        L               <scalar>;

        // Optional entries
        Cn              <scalar>;
        emissivity      <scalar>;
    }
    \endverbatim

    where the entries mean:
    \table
      Property  | Description                         | Type | Reqd | Deflt
      type      | Type name: Bromley                  | word | yes  | -
      L         | Characteristic length scale       | scalar | yes  | -
      Cn  | Coefficient for nucleation site density | scalar | no   | 0.62
      emissivity | Wall emissivity                  | scalar | no   | 1.0
    \endtable
