static Scalar Dumux::BinaryCoeff::H2O_CH4::henry ( Scalar  temperature )

inlinestatic

Henry coefficient \([N/m^2]\) for molecular methane in liquid water.

See:

IAPWS: "Guideline on the Henry's Constant and Vapor-Liquid Distribution Constant for Gases in H2O and D2O at High Temperatures" http://www.iapws.org/relguide/HenGuide.pdf

liquidDiffCoeff()

template<class Scalar >

static Scalar Dumux::BinaryCoeff::H2O_CH4::liquidDiffCoeff ( Scalar  temperature, Scalar  pressure  )

inlinestatic

Diffusion coefficient \(\mathrm{[m^2/s]}\) for molecular methane in liquid water.

Parameters

temperature	the temperature \(\mathrm{[K]}\)
pressure	the phase pressure \(\mathrm{[Pa]}\)

The empirical equations for estimating the diffusion coefficient in infinite solution which are presented in Reid, 1987 [61] all show a linear dependency on temperature. We thus simply scale the experimentally obtained diffusion coefficient of Ferrell and Himmelblau by the temperature.
This function use an interpolation of the data by [79] http://dx.doi.org/10.1021/j100895a017
