Class
    Foam::compressible::thermalBaffle1DFvPatchScalarField
 
Group
    grpThermoBoundaryConditions
 
Description
    This BC solves a steady 1D thermal baffle.
 
    The solid properties are specify as dictionary. Optionally radiative heat
    flux (qr) can be incorporated into the balance. Some under-relaxation might
    be needed on qr.  Baffle and solid properties need to be specified on the
    master side of the baffle.
 
Usage
    Example of the boundary condition specification using constant
    solid thermo :
 
    \verbatim
    <masterPatchName>
    {
        type   compressible::thermalBaffle1D<hConstSolidThermoPhysics>;
        samplePatch     <slavePatchName>;
 
        thickness       uniform 0.005;  // thickness [m]
        qs              uniform 100;    // heat flux [W/m2]
 
        qr              none;
        relaxation      1;
 
        // Solid thermo
        specie
        {
            molWeight       20;
        }
        transport
        {
            kappa           1;
        }

        {
            Hf              0;
            Cp              10;
        }
        equationOfState
        {
            rho             10;
        }
 
        value               uniform 300;
    }
 
    <slavePatchName>
    {
        type   compressible::thermalBaffle1D<hConstSolidThermoPhysics>;
        samplePatch     <masterPatchName>;
 
        qr              none;
        relaxation      1;
    }
