TwoPhaseNCGPartialPressureFluidProperties

This fluid properties class is used for two-phase fluids that have a single, non-condensable gas (NCG) mixed with their vapor phase. The vapor mixture model of IdealRealGasMixtureFluidProperties is used, which corresponds to a partial pressure mixture model for real gases.

In addition to the interfaces of its parent class, this class provides an interface for computing the mass fraction of the NCG ξNCG\xi_\text{NCG} assuming saturation of the main fluid at the temperature TT and mixture pressure pp. The molar fraction of the NCG ψNCG\psi_\text{NCG} is computed by combining the two relations:

p=pv,sat(T)+pNCG,p = p_{v,\text{sat}}(T) + p_\text{NCG} \,,pNCG=ψNCGp,p_\text{NCG} = \psi_\text{NCG} p \,,

which with the relation between molar fractions and mass fractions, yields

ψNCG=ppv,sat(T)p,\psi_\text{NCG} = \frac{p - p_{v,\text{sat}}(T)}{p} \,,ξNCG=MNCGM,\xi_\text{NCG} = \frac{M_\text{NCG}}{M} \,,

where MNCGM_\text{NCG} is the NCG molar mass, and MM is the mixture molar mass,

M=(1ψNCG)Mv+ψNCGMNCG,M = (1 - \psi_\text{NCG}) M_v + \psi_\text{NCG} M_\text{NCG} \,,

with MvM_v denoting the main fluid molar mass.
