Description

Binary coefficients.

Binary coefficients describe the relations of a mixture of two components. Typical binary coefficients are Henry coefficients or binary molecular diffusion coefficients. So far, the programming interface for accessing binary coefficients has not been standardized in Dumux.

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

inline

Estimate binary diffusion coefficients \(\mathrm{[m^2/s]}\) in gases according to the method by Fuller.

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.

henryIAPWS()

template<class Scalar >

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

inline

The Henry constants in liquid water using the IAPWS 2004 formulation.

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:

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.
