◆ gasHeatCapacity()

template<class Scalar >

template<class Evaluation >

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

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 $\mathrm{[Pa]}$
