Class
    Foam::wallBoilingModels::filmBoilingModels::BreenWestwater

Description
    Boiling film correlation.
    A correlation for boiling film modelling
    based on Breen & Westwater (1965) for boiling flows.

    References:
    \verbatim
        Breen B.P. & Westwater J. W. (1965)
        Effect of diameter of horizontal
        tubes on film boiling heat tranfer.
        Chem. Eng. Progr. 58. No 7.
    \endverbatim

Usage
    Example of the model specification:
    \verbatim
    filmBoilingModel
    {
        // Mandatory entries
        type            BreenWestwater;

        // Optional entries
        Cn              <scalar>;
        an              <scalar>;
        bn              <scalar>;
        n               <scalar>;
    }
    \endverbatim

    where the entries mean:
    \table
      Property   | Description                       | Type | Reqd | Deflt
      type       | Type name: BreenWestwater         | word | yes  | -
      Cn         | Model coefficient               | scalar | no   | 0.37
