Test of two-phase heat transfer components
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
The test demonstrates that the computed heat flows change continuously with the node enthalpies and the flow rate, as required to guarantee the existence and uniqueness of the DAE solution.
