radiativeConvectiveSinkFvPatchScalarField

Description

Heat sink boundary for solid temperature defined by radiative and convective heat transfer coefficients.

Options

The radiativeConvectiveSink fvPatchField can be selected in the patch subdictionary inside the boundaryField subdictionary of the temperature field.

Parameters in the patch subdictionary for radiativeConvectiveSink:

kappa The name of the conductivity field. By default, it is set to "k", which is the field name for conductivity used by the OFFBEAT material class.
alpha Specifies the value of the gap conductance field in \(W/K/m^2\). This can either be a nonUniformList<scalar> with a value defined for each face, or a uniform field with a single value applied across all faces.
emissivity Specifies the value of the emissivity field. This can either be a nonUniformList<scalar> with a value defined for each face, or a uniform field with a single value applied across all faces.
value Specifies the initial value of the patch temperature field.

Usage

cladOuter

    type            radiativeConvectiveSink;

    // Sink temperature
    T0              uniform 600;
    // Convective heat transfer coefficient
    alpha           uniform 50000;
    // Radiative emissivity
    emissivity      uniform 0.5;

    value           $internalField;
