calc_alpha0_deriv_nocache()

		const CoolPropDbl &	tau,
		const CoolPropDbl &	delta,
		const CoolPropDbl &	Tr,
		const CoolPropDbl &	rhor
	)

Take derivatives of the ideal-gas part of the Helmholtz energy, don't use any cached values, or store any cached values.

Parameters

nTau	How many derivatives with respect to \(\tau\) to take
nDelta	How many derivatives with respect to \(\delta\) to take
mole_fractions	Mole fractions
tau	Reciprocal reduced temperature where \(\tau=T_r / T\)
delta	Reduced density where \(\delta = \rho / \rho_r \)
Tr	Reducing temperature of the mixture [K]
rhor	Reducing molar density of the mixture [mol/m^3]

\[ \alpha^0 = \displaystyle\sum_{i=1}^{N}x_i[\alpha^0_{oi}(\rho,T) + \ln x_i] \]

where in this case, we use the \(\alpha^0\) for the given fluid, which uses the inputs \(\tau_i\) and \(\delta_i\), so we do the conversion between mixture and component reduced states with

\[ \tau_i = \frac{T_{c,i}}{T} = \frac{\tau T_{c,i}}{T_r} \]

\[ \delta_i = \frac{\rho}{\rho_{c,i}} = \frac{\delta\rho_r}{\rho_{c,i}} \]
