Class
    Foam::compressible::
        turbulentTemperatureCoupledBaffleMixedFvPatchScalarField

Description
    Mixed boundary condition for temperature, to be used for heat-transfer
    on back-to-back baffles. Optional thin thermal layer resistances can be
    specified through thicknessLayers and kappaLayers entries.

    Specifies gradient and temperature such that the equations are the same
    on both sides:
      - refGradient = qs_/kappa
      - refValue = neighbour value
      - mixFraction = nbrKDelta/(nbrKDelta + myKDelta())

    where KDelta is heat-transfer coefficient K*deltaCoeffs
    and qs is the optional source heat flux.

    The thermal conductivity \c kappa can either be retrieved from various
    possible sources, as detailed in the class temperatureCoupledBase.

Usage
    \table
        Property     | Description             | Required    | Default value
        Tnbr         | name of the field       | no          | T
        thicknessLayers | list of thicknesses per layer [m] | no |
        kappaLayers  | list of thermal conductivities per layer [W/m/K] | no |
        qs           | Optional source heat flux [W/m^2] | no | 0
        Qs           | Optional heat source [W]          | no | 0
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            compressible::turbulentTemperatureCoupledBaffleMixed;
        Tnbr            T;
        thicknessLayers (0.1 0.2 0.3 0.4);
        kappaLayers     (1 2 3 4);
        qs              uniform 100;    // Optional source heat flux [W/m^2]
        value           uniform 300;
    }
    \endverbatim

    Needs to be on underlying mapped(Wall)FvPatch.

    Note that in order to provide an optional heat source either qs or Qs
    should be specified, not both.
