Member Function Documentation

◆ criticalPressure()

template<class Scalar >
static Scalar Dumux::Components::CH4< Scalar >::criticalPressure ( )
inlinestatic

Returns the critical pressure \(\mathrm{[Pa]}\) of molecular methane.

◆ criticalTemperature()

template<class Scalar >
static Scalar Dumux::Components::CH4< Scalar >::criticalTemperature ( )
inlinestatic

Returns the critical temperature \(\mathrm{[K]}\) of molecular methane.

◆ gasDensity()

template<class Scalar >
static Scalar Dumux::Components::CH4< Scalar >::gasDensity ( Scalar  temperature,
Scalar  pressure 
)
inlinestatic

The density \(\mathrm{[kg/m^3]}\) of \(CH_4\) gas at a given pressure and temperature.

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

◆ gasEnthalpy()

template<class Scalar >
static const Scalar Dumux::Components::CH4< Scalar >::gasEnthalpy ( Scalar  temperature,
Scalar  pressure 
)
inlinestatic

Specific enthalpy \(\mathrm{[J/kg]}\) of pure methane gas.

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

◆ gasHeatCapacity()

template<class Scalar >
static Scalar Dumux::Components::CH4< Scalar >::gasHeatCapacity ( Scalar  T,
Scalar  pressure 
)
inlinestatic

Specific isobaric heat capacity \(\mathrm{[J/(kg*K)]}\) of pure methane gas.

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

See: R. Reid, et al. (1987, pp 154, 657, 665) [53]

◆ gasInternalEnergy()

template<class Scalar >
static const Scalar Dumux::Components::CH4< Scalar >::gasInternalEnergy ( Scalar  temperature,
Scalar  pressure 
)
inlinestatic

Specific enthalpy \(\mathrm{[J/kg]}\) of pure methane 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 \(\mathrm{[Pa]}\)
