Thermodynamic property data for pressure p and temperature T as dynamic states
Extends from Modelica.Icons.Record (Icon for records).
Information
Model description
A base class for medium property models which use pressure and temperature as dynamic states. This is a reasonable model for fluids that can also be in the gas and liquid regions, but never in the two-phase region.
