Class
    Foam::heatTransferCoeffModels::fixedReferenceTemperature
 
Description
    Heat transfer coefficient calculation that employs a fixed reference
    temperature.
 
    The heat transfer coefficient is calculated by:
 
    \f[
        h = \frac{q}{T_{ref} - T_p}
    \f]
 
    where
    \vartable
      h       | Heat transfer coefficient                         [W/m^2/K]
      q       | Heat flux                                         [W/m^2]
      T_{ref} | User-specified reference temperature              [K]
      T_p     | Patch temperature field                           [K]
    \endvartable
 
Usage
    Minimal example by using \c system/controlDict.functions:
    \verbatim
    heatTransferCoeffFO
    {
        // Inherited entries
        ...
 
        // Mandatory entries
        htcModel        fixedReferenceTemperature;
        Tref            <scalar>;
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property  | Description                            | Type | Reqd | Deflt
      type      | Model name: fixedReferenceTemperature  | word | yes  | -
      Tref      | User-specied reference temperature   | scalar | yes  | -
    \endtable
