A New Macroscopic Model for One-Phase Miscible Flow in Heterogeneous Media

Presently, the most attractive empirical models for representing macroscopically viscous fingering behavior in miscible displacements are from Fayers, Jouaux, and Tchelepi and from Todd and Longstaff named hereafter respectively FJT model and T&L model. Although successful in representing most of the cases investigated in their paper, the FJT formulation requires two phases and two components to represent the behavior of a single non ideally mixed phase with two components.
