Emulsion flow in porous media has garnered significant attention for its potential to enhance oil recovery. While the Jamin effect can improve mobility during emulsion flooding, it also lead droplet retention. In this work, we investigate of applying an electric field modulate and thereby achieve reduced The charged droplet's electrophoretic motion under applied is numerically simulated. This study analyzes behavior droplets as they traverse constricted microcapillary channels models. results indicate that reduce resistance (expressed factor) channel from 1.458 1.349. addition, when encountering obstruction, exhibit varying regimes (passing or breaking) are influenced by their size associated electrical capillary number. Remarkably, was found reduces retention two distinct ways: (i) assisting through throat small numbers; (ii) forcing breakup high numbers. Furthermore, permeability medium increases 2.31 Darcy at CaE = 0 3.42 233.96 due droplets. These findings provide valuable insights into role electrophoresis improving reducing entrapment.
