Modelica.Media

Library of media property models

Information

This library contains interface definitions for media and the following property models for single and multiple substance fluids with one and multiple phases:

• Ideal gases:
  1241 high precision gas models based on the NASA Glenn coefficients, plus ideal gas mixture models based on the same data.
• Water models:
  ConstantPropertyLiquidWater, WaterIF97 (high precision water model according to the IAPWS/IF97 standard)
• Air models:
  SimpleAir, DryAirNasa, ReferenceAir, MoistAir, ReferenceMoistAir.
• Incompressible media:
  TableBased incompressible fluid models (properties are defined by tables rho(T), HeatCapacity_cp(T), etc.)
• Compressible liquids:
  Simple liquid models with linear compressibility
• Refrigerant Tetrafluoroethane (R134a).

The following parts are useful, when newly starting with this library:

• Modelica.Media.UsersGuide.
• Modelica.Media.UsersGuide.MediumUsage describes how to use a medium model in a component model.
• Modelica.Media.UsersGuide.MediumDefinition describes how a new fluid medium model has to be implemented.
• Modelica.Media.UsersGuide.ReleaseNotes summarizes the changes of the library releases.
• Modelica.Media.Examples contains examples that demonstrate the usage of this library.
