modelSteamSaturationConsistencyCheck
Model that checks the consistency of saturated property functions
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This example checks the consistency of satuated property functions across the steam and liquid water mediums. It also checks if the inversion of saturated temperature and saturated pressure is implemented correctly for the steam model.
Errors are presented as percent differences between the standard property functions - e.g medium.specificEnthalpy(saturatedState) - and the IF97 saturated property functions as the baseline.
