Description

template<class Scalar, class CO2Component, class H2OType = Components::TabulatedComponent<Components::H2O<Scalar>>, class Policy = BrineCO2DefaultPolicy<true>>
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.

inlinestatic

Molecular diffusion of a component $\kappa$ is caused by a gradient of the chemical potential and follows the law

$$J=-D\mathrm{\nabla }m{u}_{\kappa }$$

where ${\mu }_{\kappa }$ 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

$${\mu }_{\kappa }=R{T}_{\alpha }\ln \frac{f_{\kappa }}{p_{\alpha }}$$

where ${\mathrm{p}}_{\alpha }$ and ${\mathrm{T}}_{\alpha }$ are the fluid phase' pressure and temperature.

isIdealMixture()

template<class Scalar , class CO2Component , class H2OType = Components::TabulatedComponent<Components::H2O<Scalar>>, class Policy = BrineCO2DefaultPolicy<true>>

static bool Dumux::FluidSystems::BrineCO2< Scalar, CO2Component, H2OType, Policy >::isIdealMixture ( int  phaseIdx )

inlinestatic

We define an ideal mixture as a fluid phase where the fugacity coefficients of all components times the pressure of the phase are independent on the fluid composition. This assumption is true if Henry's law and Raoult's law apply. If you are unsure what this function should return, it is safe to return false. The only damage done will be (slightly) increased computation times in some cases.

Parameters

phaseIdx

The index of the fluid phase to consider

isMiscible()
