Class
    Foam::heatTransferCoeffModels::localReferenceTemperature

Description
    Heat transfer coefficient calculation that employs
    the patch internal field as the reference temperature.

    The heat transfer coefficient is calculated by:

    \f[
        h = \frac{q}{T_c - T_p}
    \f]

    where
    \vartable
      h       | Heat transfer coefficient                         [W/m^2/K]
      q       | Heat flux                                         [W/m^2]
      T_c     | Patch internal temperature field                  [K]
      T_p     | Patch temperature                                 [K]
    \endvartable

Usage
    Minimal example by using \c system/controlDict.functions:
    \verbatim
    heatTransferCoeff1
    {
        // Inherited entries
        ...

        // Mandatory entries
        htcModel        localReferenceTemperature;
    }
    \endverbatim

    where the entries mean:
    \table
      Property  | Description                            | Type | Reqd | Deflt
      type      | Model name: localReferenceTemperature  | word | yes  | -
    \endtable
