Member Function Documentation

◆ gasDensity()

template<class Scalar >
template<class Evaluation >
static Evaluation Opm::N2< Scalar >::gasDensity ( const Evaluation &  temperature,
const Evaluation &  pressure 
)
inlinestatic

The density $\mathrm{[kg/m^3]}$ of $N_2$ gas at a given pressure and temperature.

Parameters
temperaturetemperature of component in $\mathrm{[K]}$
pressurepressure of component in $\mathrm{[Pa]}$

◆ gasEnthalpy()

template<class Scalar >
template<class Evaluation >
static Evaluation Opm::N2< Scalar >::gasEnthalpy ( const Evaluation &  temperature,
const Evaluation &   
)
inlinestatic

Specific enthalpy $\mathrm{[J/kg]}$ of pure nitrogen gas.

Parameters
temperaturetemperature of component in $\mathrm{[K]}$
pressurepressure of component in $\mathrm{[Pa]}$

See: R. Reid, et al.: The Properties of Gases and Liquids, 4th edition, McGraw-Hill, 1987, pp 154, 657, 665

◆ gasHeatCapacity()

template<class Scalar >
template<class Evaluation >
static Evaluation Opm::N2< Scalar >::gasHeatCapacity ( const Evaluation &  temperature,
const Evaluation &   
)
inlinestatic

Specific isobaric heat capacity $[J/(kg K)]$ of pure nitrogen gas.

This is equivalent to the partial derivative of the specific enthalpy to the temperature.

◆ gasInternalEnergy()

template<class Scalar >
template<class Evaluation >
static Evaluation Opm::N2< Scalar >::gasInternalEnergy ( const Evaluation &  temperature,
const Evaluation &  pressure 
)
inlinestatic

Specific enthalpy $\mathrm{[J/kg]}$ of pure nitrogen gas.

   Definition of enthalpy: \f$h= u + pv = u + p / \rho\f$.

   Rearranging for internal energy yields: \f$u = h - pv\f$.

   Exploiting the Ideal Gas assumption (\f$pv = R_{\textnormal{specific}} T\f$)gives: \f$u = h - R / M T \f$.

   The universal gas constant can only be used in the case of molar formulations.
Parameters
temperaturetemperature of component in $\mathrm{[K]}$
pressurepressure of component in $\mathrm{[Pa]}$
