Detailed Description

template<class Scalar, class WettingPhase, class NonwettingPhase>
class Opm::FluidSystems::TwoPhaseImmiscible< Scalar, WettingPhase, NonwettingPhase >

A fluid system for two-phase models assuming immiscibility and thermodynamic equilibrium.

The wetting and the non-wetting phase can be defined individually via Opm::LiquidPhase<Component> and Opm::GasPhase<Component>. These phases consist of one pure component. With the help of this adapter class, the phase properties can be accessed. This is suitable for pure two-phase systems without compositional effects.

Member Typedef Documentation

template<class Scalar , class WettingPhase , class NonwettingPhase >
typedef NullParameterCache Opm::FluidSystems::TwoPhaseImmiscible< Scalar, WettingPhase, NonwettingPhase >::ParameterCache

The type of the fluid system's parameter cache.

The parameter cache can be used to avoid re-calculating expensive parameters for multiple quantities. Be aware that what the parameter cache actually does is specific for each fluid system and that it is opaque outside the fluid system.

unsigned  ,
unsigned   
)
inlinestaticinherited

Calculate the binary molecular diffusion coefficient for a component in a fluid phase [mol^2 * s / (kg*m^3)].

Molecular diffusion of a compoent $\kappa$ is caused by a gradient of the mole fraction and follows the law

\[ J = - D \mathbf{grad} x^\kappa_\alpha \]

where $x_\alpha^\kappa$ is the component's mole fraction in phase $\alpha$, $D$ is the diffusion coefficient and $J$ is the diffusive flux.

const ParameterCache &  ,
unsigned  phaseIdx,
unsigned  compIdx 
)
inlinestatic

Calculate the fugacity coefficient [Pa] of an individual component in a fluid phase.

The fugacity coefficient $\phi_\kappa$ is connected to the fugacity $f_\kappa$ and the component's molarity $x_\kappa$ by means of the relation

\[ f_\kappa = \phi_\kappa\,x_{\kappa} \]

static bool Opm::FluidSystems::TwoPhaseImmiscible< Scalar, WettingPhase, NonwettingPhase >::isCompressible ( unsigned  phaseIdx)
inlinestatic

Returns true if and only if a fluid phase is assumed to be compressible.

Compressible means that the partial derivative of the density to the fluid pressure is always larger than zero.

template<class Scalar , class WettingPhase , class NonwettingPhase >
static bool Opm::FluidSystems::TwoPhaseImmiscible< Scalar, WettingPhase, NonwettingPhase >::isIdealGas ( unsigned  phaseIdx)

Returns true if and only if a fluid phase is assumed to be an ideal gas.

template<class Scalar , class WettingPhase , class NonwettingPhase >
static bool Opm::FluidSystems::TwoPhaseImmiscible< Scalar, WettingPhase, NonwettingPhase >::isIdealMixture ( unsigned  )
inlinestatic

Returns true if and only if a fluid phase is assumed to be an ideal mixture.

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 Rault'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.
