Hindered transport of spherical particles in cylindrical pores: The role of structural heterogeneity in rejection-permeability trade-offs
Debanik Bhattacharjee, Yaniv Edery, Guy Z. Ramon
Membrane separations rely on balancing rejection and permeability. Extensive work has clarified how pore structure and operating conditions control each quantity in idealized or we…

Spatio-temporal dynamics of surfactant driven secondary invasion in Gaussian pore networks
Debanik Bhattacharjee, Guy Z. Ramon, Yaniv Edery
Capillarity-dominated two-phase displacement in porous media often continues beyond the initial invasion-percolation (IP) breakthrough, as surfactants alter interfacial properties…

The evolution of invasion patterns due to surfactant adsorption in anomalous pore distribution: Role of Mass Transfer and Laplace Pressure
Debanik Bhattacharjee, Guy Z. Ramon, Yaniv Edery
Here, we develop a time-dependent pore network model (PNM) to simulate the effects of surfactant-induced IFT reduction on immiscible displacement driven by constant inlet pressure,…
