modelConductionElement

Model of quasi-sationary mass and heat transfer

Extends from Internal.PartialConductionElement.

Information

Undirected implementation of the Conduction Element.

This model is an element with a fixed volume (fig. 1). The mass in the volume is assumed quasi-stationary (statically computed with volume and density), and the fore massflow is coupled to the rear massflow.

Because of this the ConductionElement cannot be used as a loop breaker.

The advantage is that multiple ConductionElements can be put behind each other without worrying about oscillations or fast eigenvalues between their masses. The ConductionElement implements equations for conservation of mass and energy for the fluid mass contained within it.

For further documentation see the documentation of the motherclass.
