Use the Wall Heat Transfer node to set up heat exchange across the pipe wall. Define the external temperature and the nature of the heat transfer. The
Internal Film Resistance,
Wall Layer, and
External Film Resistance subnodes are available from the context menu (right-click the parent node) or from the
Physics toolbar,
Attributes menu. These compute heat transfer coefficients based on the section
Theory for the Heat Transfer in Pipes Interface.
Enter a value for the External Temperature Text (SIĀ unit: K). If an expression is used for
Text that is a locally defined variable on the edge, the check box
Take average in adjacent domain should be cleared.
Use the Pipe Wall Heat Transfer multiphysics coupling if the temperature in surrounding 3D solid physics is calculated using
Heat Transfer interface.
