turbulentTemperatureRadCoupledMixed

Description

The turbulentTemperatureRadCoupledMixed is a boundary condition that provides a 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.

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

Usage

The condition requires entries in both the boundary and field files.

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            compressible::turbulentTemperatureRadCoupledMixed;
    Tnbr            <word>;

    // 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>;
    ...
}
