ReferenceAir.Air_dT: Detailed dry air model (130 ... 2000 K) explicit in d and T
The package Air_dT can be used as any other medium model (see User's Guide of Media Library for further information).
Extends from Modelica.Icons.MaterialProperty (Icon for property classes), Modelica.Media.Air.ReferenceAir.Air_Base (Properties of dry air calculated using the equation of state by Lemmon et. al.).
