Relations for binary mixtures

Binary coefficients such as binary diffusion coefficients, Henry coefficients. More...

Function Documentation

fullerMethod()

template<class Scalar>

Scalar Dumux::BinaryCoeff::fullerMethod ( const Scalar * M, const Scalar * SigmaNu, const Scalar temperature, const Scalar pressure )

inline

Parameters

M	molar masses \(\mathrm{[g/mol]}\)
SigmaNu	atomic diffusion volume
temperature	The temperature \(\mathrm{[K]}\)
pressure	phase pressure \(\mathrm{[Pa]}\)

This function estimates the diffusion coefficients in binary gases using to the method proposed by Fuller. This method and is only valid at "low" pressures.

See: R. Reid, et al. (1987, pp. 587-588) [69]

henryIAPWS()

template<class Scalar>

Scalar Dumux::henryIAPWS ( Scalar E, Scalar F, Scalar G, Scalar H, Scalar temperature )

inline

Parameters

E	Correlation parameter
F	Correlation parameter
G	Correlation parameter
H	Correlation parameter
temperature	the temperature \(\mathrm{[K]}\)

This function calculates \(\mathrm{K_D}\), see:

IAPWS: "Guideline on the Henry's Constant and Vapor-Liquid Distribution Constant for Gases in H2O and D2O at High Temperatures" Equation (5) [86]

Range of validity: T = {278.12 ; 636.46} approximations beyond this range are increasingly incorrect. However, close to the critical the values are more, again.
