Thermophysical models

There is clearly a need to represent the true behaviour of liquids and gases in our simulations.

OpenFOAM is distributed with a huge library of thermophysical models and properties that can read data from standard tables, including liquid and gas properties, combustion and flame speed models.

Basic thermophysical models

hThermo	General thermophysical model calculation based on enthalpy $h \special {t4ht=$

pureMixture	General thermophysical model calculation for passive gas mixtures

Combustion models

hMixtureThermo	Calculates enthalpy for combustion mixture
hhuMixtureThermo	Calculates enthalpy for unburnt gas and combustion mixture

homogeneousMixture	Combustion mixture based on normalised fuel mass fraction $b \special {t4ht=$
inhomogeneousMixture	Combustion mixture based on $b \special {t4ht=$ and total fuel mass fraction $ft \special {t4ht=$
veryInhomogeneousMixture	Combustion mixture based on $b \special {t4ht=$ , $ft \special {t4ht=$ and unburnt fuel mass fraction $fu \special {t4ht=$
