A compositional fluid with brine (H2O & NaCl) and carbon dioxide as components in both the liquid and the gas (supercritical) phase.

class Dumux::FluidSystems::BrineCO2< Scalar, CO2Component, H2OType, Policy >
- Note
- Depending on the chosen policy, the salinity is assumed to be constant (in which case Brine is used as a pseudo component) or salt (here NaCl) is considered as an individual component.
-
This implementation always assumes NaCl stays in the liquid phase.

Molecular diffusion of a component \(\mathrm{\kappa}\) is caused by a gradient of the chemical potential and follows the law
\[ J = - D \nabla mu_\kappa \]
where \(\mathrm{\mu_\kappa}\) is the component's chemical potential, \(D\) is the diffusion coefficient and \(\mathrm{J}\) is the diffusive flux. \(\mathrm{mu_\kappa}\) is connected to the component's fugacity \(\mathrm{f_\kappa}\) by the relation
\[ \mu_\kappa = R T_\alpha \mathrm{ln} \frac{f_\kappa}{p_\alpha} \]
where \(\mathrm{p_\alpha}\) and \(\mathrm{T_\alpha}\) are the fluid phase' pressure and temperature.
