Detailed Description

The IdealGas class implements the equation of state for an ideal gas.

Member Function Documentation

virtual double IdealGas::calculateCompressibility	(	const double	,
		const double
	)		const

inlineoverridevirtual

Override. Independent of pressure and temperature.

virtual arma::vec IdealGas::evaluate	(	const double	,
		const double
	)		const

inlineoverridevirtual

Override. Independent of pressure and temperature.

The compressibility is 1, derivatives are zero, and the heat capacities are the heat capacities of an ideal monoatomic gas.

Returns: Z = 1, derivatives = 0 and \(c_p\) and \(c_v\) of an ideal monoatomic gas.
