fugacity_coefficients#

class FugacityCoefficients[source]#

Abstract class for the estimation of fugacity coefficients. Non-abstract subclasses should implement the following methods:

__init__(self, chemicals: Iterable[Chemical]):: Should use pure component data from chemicals to setup future calculations of fugacity coefficients.
__call__(self, y: 1d array, T: float, P:float):: Should accept an array of vapor molar compositions y, temperature T (in Kelvin), and pressure P (in Pascal), and return an array of fugacity coefficients. Note that the molar compositions must be in the same order as the chemicals defined when creating the FugacityCoefficients object.

class IdealFugacityCoefficients(chemicals)[source]#

Create an IdealFugacityCoefficients object that estimates all fugacity coefficients to be 1 when called with composition, temperature (K), and pressure (Pa).

Parameters:: chemicals (Iterable[Chemical])

property chemicals#: tuple[Chemical] All chemicals involved in the calculation of fugacity coefficients.

__call__(y, T, P)[source]#: Call self as a function.
