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 = zero gradient
      - refValue = neighbour value
      - mixFraction = nbrKDelta / (nbrKDelta + myKDelta())

    where KDelta is heat-transfer coefficient K * deltaCoeffs

    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 |
        kappaMethod  | inherited from temperatureCoupledBase | inherited |
        kappa        | inherited from temperatureCoupledBase | inherited |
    \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);
        kappaMethod     lookup;
        kappa           kappa;
        value           uniform 300;
    }
    \endverbatim

    Needs to be on underlying mapped(Wall)FvPatch.
