Calculation of fluid properties of air in the fluid region of 130 Kelvin to 2000 Kelvin at pressures up to 2000 MPa. To use this package in your model, select Air_dT, Air_pT or Air_ph according to which variables you choose to determine your state.
The functions provided by this package shall be used inside of the restricted limits according to the referenced literature.
The verification report for the development of this library is provided here.
This library was developed by XRG Simulation GmbH as part of the Clean Sky JTI project (Project title: MoMoLib-Modelica Model Library Development for Media, Magnetic Systems and Wavelets; Project number: 296369; Theme: JTI-CS-2011-1-SGO-02-026: Modelica Model Library Development Part I). The partial financial support for the development of this library by the European Union is highly appreciated.
