Thermodynamic property data for density d 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 density and temperature as dynamic states. This is a reasonable model for fluids that can be in the gas, liquid and two-phase region. The model is numerically not well suited for liquids except if the pressure is always above approx. 80% of the critical pressure. ## Copyright © EDF 2002 - 2025 ## ThermoSysPro Version 4.2
