Modelica.Media.Air.ReferenceAir

ReferenceAir: Detailed dry air model with a large operating range (130 ... 2000 K, 0 ... 2000 MPa) based on Helmholtz equations of state

Information




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.




Restriction



The functions provided by this package shall be used inside of the restricted limits according to the referenced literature.
