IdealMixtureModel

class thermosteam.mixture.IdealMixtureModel(models, var)[source]

Create an IdealMixtureModel object that calculates mixture properties based on the molar weighted sum of pure chemical properties.

Parameters

  • models (Iterable[function(T, P)]) – Chemical property functions of temperature and pressure.

  • var (str) – Description of thermodynamic variable returned.

Notes

Mixture objects can contain IdealMixtureModel objects to establish as mixture model for thermodynamic properties.

Examples

>>> from thermosteam.mixture import IdealMixtureModel
>>> from thermosteam import Chemicals
>>> chemicals = Chemicals(['Water', 'Ethanol'])
>>> models = [i.Psat for i in chemicals]
>>> mixture_model = IdealMixtureModel(models, 'Psat')
>>> mixture_model
<IdealMixtureModel(mol, T, P=None) -> Psat [Pa]>
>>> mixture_model([0.2, 0.8], 350)
