Class
    Foam::heatTransferCoeffModels::localReferenceTemperature
 
Description
    Heat transfer coefficient calculation that employs
    the patch internal field as the reference temperature.
 
    The heat transfer coefficient is specified by:
 
    \f[
        h = \frac{q}{T_c - T_w}
    \f]
 
    where
    \vartable
      h       | Convective heat transfer coefficient of the flow  [W/(m2 K)]
      q       | Heat flux                                         [W/m2]
      T_{ref} | Reference temperature of patch internal field     [K]
      T_w     | Patch temperature                                 [K]
    \endvartable
 
Usage
    Minimal example by using \c system/controlDict.functions:
    \verbatim
    heatTransferCoeff1
    {
        // Mandatory and other optional entries
        ...
        htcModel        localReferenceTemperature;
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property  | Description                            | Type | Reqd | Dflt
      type      | Model name: localReferenceTemperature  | word | yes  | -
    \endtable
