The Radiation in Participating Media Interface
The Radiation in Participating Media (rpm) interface (), found under the Heat Transfer>Radiation branch (), is used to model radiative heat transfer inside participating (semi-transparent media) media.
Whereas The Heat Transfer with Radiation in Participating Media Interface computes the temperature field, this physics interface requires it as a model input. If the medium does not participate in the radiation (transparent medium), then use The Surface-To-Surface Radiation Interface instead.
The radiative intensity equations defined in participating media domains correspond to a P1 approximation or to the discrete ordinates method approximation equations depending on the selected approximation.
When the physics interface is added, these default nodes are added to the Model Builder: Radiation in Participating Media, Wall, Continuity on Interior Boundary, and Initial Values. Right-click the main node to add boundary conditions or other features. Then, from the Physics toolbar, add other nodes that implement, for example, boundary conditions. You can also right-click Radiation in Participating Media node to select physics features from the context menu.
