Class
    Foam::fv::heatExchangerSource
 
Group
    grpFvOptionsSources
 
Description
    Heat exchanger source model for compressible flows, where the heat
    exchanger is modelled as an energy source using a selection of cells.
 
    Sources applied to either of the below, if exist:
    \verbatim
      e         | Internal energy                            [m2/s2]
      h         | Enthalphy                                  [m2/s2]
    \endverbatim
 
    Required fields:
    \verbatim
      T         | Temperature                                [K]
      U         | Velocity                                   [m/s]
      phi       | Mass flux                                  [kg/s]
    \endverbatim
 
Usage
    Minimal example by using \c constant/fvOptions:
    \verbatim
    <name>
    {
        // Mandatory entries
        type                     heatExchangerSource;
        model                    <word>;
        faceZone                 <word>;
 
        // Conditional entries
 
            // Option-1: when model == effectivenessTable
 
            // Option-2: when model == referenceTemperature
 
        // Optional entries
        U                        <word>;
        T                        <word>;
        phi                      <word>;
 
        // Inherited entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property  | Description                       | Type  | Reqd | Deflt
      type      | Type name: heatExchangerSource    | word  | yes  | -
      model     | Name of the heat exchanger model  | word  | yes  | -
      faceZone  | Name of the faceZone at the heat exchanger inlet <!--
                -->                                 | word   | yes | -
      U         | Name of operand velocity field    | word   | no  | U
      T         | Name of operand temperature field | word   | no  | T
      phi       | Name of operand flux field        | word   | no  | phi
    \endtable
 
    Options for the \c model entry:
    \verbatim
      effectivenessTable    | Calculate heat exchange via an effectiveness table
      referenceTemperature  | Calculate heat exchange via a temperature table
    \endverbatim
