Detailed Description

template<class Scalar>

This class represents the Pressure-Volume-Temperature relations of the gas phase with vaporized water.

Member Function Documentation

◆ initFromState()

template<class Scalar>
void Opm::DryHumidGasPvt< Scalar >::initFromState ( const EclipseState & eclState,
const Schedule &  )

Initialize the parameters for wet gas using an ECL deck.

This method assumes that the deck features valid DENSITY and PVTGW keywords.

◆ saturationPressure()

template<class Scalar>
template<class Evaluation>
Evaluation Opm::DryHumidGasPvt< Scalar >::saturationPressure ( unsigned regionIdx,
const Evaluation & ,
const Evaluation & Rw ) const
inline

Returns the saturation pressure of the gas phase [Pa] depending on its mass fraction of the water component.

Parameters
regionIdxRegion index to use
RwThe surface volume of water component dissolved in what will yield one cubic meter of gas at the surface [-]

◆ setGasViscosity()

template<class Scalar>
void Opm::DryHumidGasPvt< Scalar >::setGasViscosity ( unsigned regionIdx,
const TabulatedTwoDFunction & mug )
inline

Initialize the viscosity of the gas phase.

This is a function of $(R_s, p_o)$...

◆ setInverseGasFormationVolumeFactor()

template<class Scalar>
void Opm::DryHumidGasPvt< Scalar >::setInverseGasFormationVolumeFactor ( unsigned regionIdx,
const TabulatedTwoDFunction & invBg )
inline

Initialize the function for the gas formation volume factor.

The gas formation volume factor $B_g$ is a function of $(p_g, X_g^O)$ and represents the partial density of the oil component in the gas phase at a given pressure.

This method sets $1/B_g(R_v, p_g)$. Note that instead of the mass fraction of the oil component in the gas phase, this function depends on the gas dissolution factor. Also note, that the order of the arguments needs to be $(R_s, p_o)$ and not the other way around.

◆ setSaturatedGasViscosity()

template<class Scalar>
void Opm::DryHumidGasPvt< Scalar >::setSaturatedGasViscosity ( unsigned regionIdx,
const SamplingPoints & samplePoints )

Initialize the phase viscosity for oil saturated gas.

The gas viscosity is a function of $(p_g, X_g^O)$, but this method only requires the viscosity of oil-saturated gas (which only depends on pressure) while there is assumed to be no dependence on the gas mass fraction...

◆ setSaturatedGasWaterVaporizationFactor()

template<class Scalar>
void Opm::DryHumidGasPvt< Scalar >::setSaturatedGasWaterVaporizationFactor ( unsigned regionIdx,
const SamplingPoints & samplePoints )
inline

Initialize the function for the oil vaporization factor $R_v$.

Parameters
regionIdxRegion index to use
samplePointsA container of (x,y) values.
