thermalBaffle1D

Description

The thermalBaffle1D is a boundary condition that 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

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

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            thermalBaffle1D;

    // Optional entries
    baffleActivated <bool>;
    qrRelaxation    <scalar>;
    qr              <word>;
    thickness       <scalarField>;
    qs              <scalarField>;
    qrPrevious      <scalarField>;

    // Inherited entries
    ...
}
