Detailed Description

Mixed boundary condition for temperature and radiation heat transfer to be used for in multiregion cases. Optional thin thermal layer resistances can be specified through thicknessLayers and kappaLayers entries.

The thermal conductivity, kappa, can either be retrieved from the mesh database using the lookup option, or from a solidThermo or fluidThermo thermophysical package.

Patch usage

Property	Description	Required	Default value
`kappa`	thermal conductivity option	yes
`kappaName`	name of thermal conductivity field	no
`Tnbr`	name of the field	no	T
`QrNbr`	name of the radiative flux in the nbr region	no	none
`Qr`	name of the radiative flux in this region	no	none
`thicknessLayers`	list of thicknesses per layer [m]	no
`kappaLayers`	list of thermal conductivites per layer [W/m/K]	no

Example of the boundary condition specification:

    myPatch
    {
        type            compressible::turbulentTemperatureRadCoupledMixed;
        Tnbr            T;
        kappa           lookup;
        KappaName       kappa;
        QrNbr           Qr; // or none. Name of Qr field on neighbour region
        Qr              Qr; // or none. Name of Qr field on local region
        thicknessLayers (0.1 0.2 0.3 0.4);
        kappaLayers     (1 2 3 4)
        value           uniform 300;
    }

Needs to be on underlying mapped(Wall)FvPatch.

Note: kappa : heat conduction at patch. Gets supplied how to lookup/calculate kappa:

'lookup' : lookup volScalarField (or volSymmTensorField) with name
'fluidThermo' : use fluidThermo and compressible::RASmodel to calculate K
'solidThermo' : use solidThermo kappa()
'directionalSolidThermo' directionalKappa()
