## Detailed Description

template<class Scalar, bool enableThermal = true>
class Opm::GasPvtMultiplexer< Scalar, enableThermal >

This class represents the Pressure-Volume-Temperature relations of the gas phase in the black-oil model.

This is a multiplexer class which forwards all calls to the real implementation.

Note that, since the main application for this class is the black oil fluid system, the API exposed by this class is pretty specific to the assumptions made by the black oil model.

## Member Function Documentation

## diffusionCoefficient()

template<class Scalar , bool enableThermal = true>
template<class Evaluation >

Evaluation Opm::GasPvtMultiplexer< Scalar, enableThermal >::diffusionCoefficient | ( | const Evaluation & | temperature,
|  | const Evaluation & | pressure,
|  | unsigned | compIdx
| ) |  | const

inline

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

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

where is the component's mole fraction in phase , is the diffusion coefficient and is the diffusive flux.

## gasPvtApproach()

template<class Scalar , bool enableThermal = true>

GasPvtApproach Opm::GasPvtMultiplexer< Scalar, enableThermal >::gasPvtApproach | ( |  | ) | const

inline

Returns the concrete approach for calculating the PVT relations.

(This is only determined at runtime.)

## saturationPressure()

template<class Scalar , bool enableThermal = true>
template<class Evaluation = Scalar>

Evaluation Opm::GasPvtMultiplexer< Scalar, enableThermal >::saturationPressure | ( | unsigned | regionIdx,
|  | const Evaluation & | temperature,
|  | const Evaluation & | Rv
| ) |  | const

inline

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

Parameters

  Rv | The surface volume of oil component dissolved in what will yield one cubic meter of gas at the surface [-]
