template<class Evaluation >

static Evaluation Opm::Air< Scalar >::gasHeatCapacity	(	const Evaluation &	temperature,
		const Evaluation &
	)

inlinestatic

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

This methods uses the formula for "zero-pressure" heat capacity that is only dependent on temperature, because the pressure dependence is rather small. This one should be accurate for a pressure of 1 atm. Values taken from NASA Contractor Report 4755, Real-Gas Flow Properties for NASA Langley Research Center Aerothermodynamic Facilities Complex Wind Tunnels using data from Hilsenrath et al 1955, "Tables of Thermal Properties of Gases"

Parameters

temperature	temperature of component in $\mathrm{[K]}$
pressure	pressure of component in $\mathrm{[Pa]}$

template<class Evaluation >

static Evaluation Opm::Air< Scalar >::gasInternalEnergy	(	const Evaluation &	temperature,
		const Evaluation &	pressure
	)

inlinestatic

Specific internal energy of $AIR$ $\mathrm{[J/kg]}$ .

Definition of enthalpy: $h= u + pv = u + p / \rho$ . Rearranging for internal energy yields: $u = h - pv$ . Exploiting the Ideal Gas assumption ( $pv = R_{\textnormal{specific}} T$ )gives: $u = h - R / M T $ .

Parameters

temperature	temperature of component in $\mathrm{[K]}$
pressure	pressure of component in $\mathrm{[Pa]}$
