Modelica.Media.Incompressible.Examples

Information

This package provides a few examples of how to construct medium models for incompressible fluids. The package contains:

• Glycol47, a model of 47% glycol water mixture, based on tables of density and heat capacity as functions of temperature.
• Essotherm650, a medium model for thermal oil, also based on tables.

Extends from Modelica.Icons.MaterialPropertiesPackage (Icon for package containing property classes).
