A Reformulation of UVN-Flash for Multicomponent Two-Phase Systems with Application to CO2-rich Mixture Transport in Pipelines
Pardeep Kumar, Patricio I. Rosen Esquivel
Pipeline transport of dense-phase CO2-rich mixtures is a crucial component in carbon capture and storage (CCS). Accurate modeling requires coupling of fluid dynamics and thermodyna…

A Fast and Robust Reformulation of the UVN-Flash Problem via Direct Entropy Maximization
Pardeep Kumar, Patricio I. Rosen Esquivel
We investigate the phase equilibrium problem for multicomponent mixtures under specified internal energy (U), volume (V), and mole numbers (N1,N2, . . . ,Nn), commonly known as the…
