GERG2008 Equation of State.

This class implements the residual contribution of the GERG2008 equation of state for multi-component systems. It is a highly accurate thermodynamic model for natural gas applications.

Parameters:

names (list, str) – List of names for the components to use in the model. Valid names are: methane, nitrogen, carbon dioxide, ethane, propane, n-butane, isobutane, n-pentane, isopentane, n-hexane, n-heptane, n-octane, nonane, decane, hydrogen, oxygen, carbon monoxide, water, hydrogen sulfide, helium, argon.

Example

from yaeos import GERG2008

model = GERG2008(["methane", "nitrogen", "carbon dioxide",])

size() → int

Return the number of components in the model.
