Dimensionless ratio of the C-component mass in -phase
to the total mass of
-phase
:
\xi_{C \alpha} (p,T) = \frac{m_{C \alpha}(p,T)}{m_\alpha(p, T) } |
It's a function of pressure and temperature
and one of the key objectives of fluid modelling.
The most important cross-phase exchange coefficients in practise are related to Solution GOR and Vaporized Oil Ratio
in Volatile Oil fluid model:
\xi_{Go} = \left( 1+\frac{1}{R_s} \frac{\rho^{\circ}_O}{\rho^{\circ}_G} \right)^{-1} |
\xi_{Og} = \left( 1+\frac{1}{R_v} \frac{\rho^{\circ}_G}{\rho^{\circ}_O} \right)^{-1} |
