Class
    Foam::incompressible::turbulentHeatFluxTemperatureFvPatchScalarField
Group
    grpIcoRASBoundaryConditions grpWallBoundaryConditions
Description
    Fixed heat boundary condition to specify temperature gradient. Input
    heat source either specified in terms of an absolute power [W], or as a
    flux [W/m^2].
    \heading Patch usage
    \table
        Property     | Description             | Required    | Default value
        heatSource   | heat source type: \c flux [W/m^2] or \c power [W]| yes |
        q            | heat source value       | yes          |
        alphaEff     | turbulent thermal diffusivity field name | yes |
    \endtable
    Example of the boundary condition specification:
    \verbatim
    myPatch
    {
        type            turbulentHeatFluxTemperature;
        heatSource      flux;
        q               uniform 10;
        alphaEff        alphaEff;
        value           uniform 300; // place holder
    }
    \endverbatim
Note
    - The units of \c alphaEff are [kg/m/s]
    - The density*specific heat capacity \c rhoCp0 (units [kg/m^3]*[J/kg/K])
      is read from the transport dictionary entry
