Description

The filmPyrolysisRadiativeCoupledMixed is boundary condition that provides a mixed boundary condition for temperature, to be used in the flow and pyrolysis regions when a film region model is used.

Usage

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

Boundary file 

<patchName>
{
    type            patch;
    ...
}

Field file 

<patchName>
{
    // Mandatory entries
    type            filmPyrolysisRadiativeCoupledMixed;
    Tnbr            <word>;
    qr              <word>;
    filmDeltaDry    <scalar>;
    filmDeltaWet    <scalar>;

    // Optional entries
    filmRegion      <word>;
    pyrolysisRegion  <word>;
    convectiveScaling  <scalar>;

    // Inherited entries
    ...
}

where:

Property Description Type Required Default
