Class

Group

Description
    This boundary condition provides a fixed heat constraint on temperature
    (i.e. \c T) to specify temperature gradient through an input heat source
    which can either be specified as absolute power [W], or as flux [W/m2].
 
    Required fields:
    \verbatim
      nut    | Turbulent viscosity                   [m2/s]
      k      | Turbulent kinetic energy              [m2/s2]
    \endverbatim
 
Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        // Mandatory entries (unmodifiable)
        type            atmTurbulentHeatFluxTemperature;
        heatSource      flux;
        alphaEff        alphaEff;
 
        // Mandatory entries (runtime modifiable)
        Cp0             0.001;
        q               uniform 10;
 
        // Optional (inherited) entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property     | Description                         | Type | Reqd  | Dflt
      heatSource   | Heat source type                    | word |  yes  | -
      alphaEff     | Name of turbulent thermal diff. field [kg/m/s] <!--
                                                     --> | word | yes   | -
      Cp0          | Specific heat capacity [m2/s2/K] <!--
                                     --> | Function1<scalar>  | yes | -
      q            | Heat source value [W (power) or W/m2 (flux)] <!--
                                     --> | PatchFunction1<scalar> | yes | -
    \endtable
 
    The inherited entries are elaborated in:
     - \link fixedGradientFvPatchScalarField.H \endlink
     - \link Function1.H \endlink
     - \link PatchFunction1.H \endlink
 
    Options for the \c heatSource entry:
    \verbatim
      power  | Absolute power heat source [W]
      flux   | Flux heat source           [W/m2]
    \endverbatim
