Class
    Foam::wallBoilingModels::departureDiameterModels::TolubinskiKostanchuk

Description
    A correlation for bubble departure diameter modelling
    based on Tolubinski-Kostanchuk (1970) for boiling flows.

    Reference:
    \verbatim
        Tolubinsky, V. I., & Kostanchuk, D. M. (1970).
        Vapour bubbles growth rate and heat transfer
        intensity at subcooled water boiling.
        In International Heat Transfer Conference 4 (Vol. 23). Begel House Inc..
    \endverbatim

Usage
    Example of the model specification:
    \verbatim
    departureDiameterModel
    {
        // Mandatory entries
        type            TolubinskiKostanchuk;

        // Optional entries
        dRef            <scalar>;
        dMax            <scalar>;
        dMin            <scalar>;
    }
    \endverbatim

    where the entries mean:
    \table
      Property  | Description                         | Type | Reqd | Deflt
      type      | Type name: TolubinskiKostanchuk     | word | yes  | -
      dRef      | Coefficient of the temperature term | scalar | no | 6e-4
      dMax      | Maximum diameter                    | scalar | no | 0.0014
      dMin      | Minimum diameter                    | scalar | no | 1e-6
    \endtable
