.Modelica.Media.IdealGases

Information

This package contains data for the 1241 ideal gases from

McBride B.J., Zehe M.J., and Gordon S. (2002): NASA Glenn Coefficients for Calculating Thermodynamic Properties of Individual Species. NASA report TP-2002-211556

Medium models for some of these gases are available in package IdealGases.SingleGases and some examples for mixtures are available in package IdealGases.MixtureGases

Using and Adapting Medium Models

The data records allow computing the ideal gas specific enthalpy, specific entropy and heat capacity of the substances listed below. From them, even the Gibbs energy and equilibrium constants for reactions can be computed. Critical data that is needed for computing the viscosity and thermal conductivity is not included. In order to add mixtures or single substance medium packages that are subtypes of Interfaces.PartialMedium (i.e., can be utilized at all places where PartialMedium is defined), a few additional steps have to be performed:

  1. All single gas media need to define a constant instance of record IdealGases.Common.SingleGasNasa.FluidConstants. For 37 ideal gases such records are provided in package IdealGases.Common.FluidData. For the other gases, such a record instance has to be provided by the user, e.g., by getting the data from a commercial or public data base. A public source of the needed data is for example the NIST Chemistry WebBook
  2. When the data is available, and a user has an instance of a FluidConstants record filled with data, a medium package has to be written. Note that only the dipole moment, the acentric factor and critical data are necessary for the viscosity and thermal conductivity functions.

Note that many properties can computed for the full set of 1241 gases listed below, but due to the missing viscosity and thermal conductivity functions, no fully Modelica.Media-compliant media can be defined.

Data records for heat capacity, specific enthalpy and specific entropy exist for the following substances and ions:
