◆ henry()

template<class Evaluation >
static Evaluation Opm::BinaryCoeff::H2O_N2::henry ( const Evaluation &  temperature)
inlinestatic

Henry coefficent $\mathrm{[N/m^2]}$ for molecular nitrogen in liquid water.

This function calculates $K_D$, see:

◆ liquidDiffCoeff()

template<class Evaluation >
static Evaluation Opm::BinaryCoeff::H2O_N2::liquidDiffCoeff ( const Evaluation &  temperature,
const Evaluation &   
)
inlinestatic

Diffusion coefficent $\mathrm{[m^2/s]}$ for molecular nitrogen in liquid water.

The empirical equations for estimating the diffusion coefficient in infinite solution which are presented in Reid, 1987 all show a linear dependency on temperature. We thus simply scale the experimentally obtained diffusion coefficient of Ferrell and Himmelblau by the temperature.
