Class
    Foam::compressible::turbulentTemperatureRadCoupledMixedFvPatchScalarField
 
Description
    Mixed boundary condition for temperature and radiation heat transfer,
    suitable for multiregion cases. The optional specification of
    thin thermal layer resistances can be made using the entries
    \c thicknessLayers and \c kappaLayers.
 
    The thermal conductivity \c kappa can be obtained from a variety
    of sources, as explained in the \c temperatureCoupledBase class.
 
Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        // Mandatory entries
        type                compressible::turbulentTemperatureRadCoupledMixed;
 
        // Optional entries
        Tnbr                <word>;
        qrNbr               <word>;
        qr                  <word>;
        logInterval         <scalar>;
        thermalInertia      <bool>;
        verbose             <bool>;
        prefix              <word>;
 
        // Conditional entries
 
            // Option-1
            thicknessLayers <scalarList>;
            kappaLayers     <scalarList>;
 
            // Option-2
            thicknessLayer  <PatchFunction1<scalar>>;
            kappaLayer      <PatchFunction1<scalar>>;
 
        // Inherited entries
        kappaMethod         <word>;
        kappa               <word>;
        ...
    }
    \endverbatim
 
    For example:
    \verbatim
    <patchName>
    {
        type            compressible::turbulentTemperatureRadCoupledMixed;
        Tnbr            T;
        qrNbr           qr; // or none. Name of qr field on neighbour region
        qr              qr; // or none. Name of qr field on this region
        thicknessLayers (0.1 0.2 0.3 0.4);
        kappaLayers     (1 2 3 4);
        thermalInertia  false/true;
        kappaMethod     lookup;
        kappa           kappa;
        value           uniform 300;
    }
    \endverbatim
 
    where the entries mean:
