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,…
Bifurcating-Paths: the relation between preferential flow bifurcations, void, and tortuosity on the Darcy scale
Avioz Dagan, Yaniv Edery
In recent years, Darcy scale transport in porous media was characterized to be Fickian or non-Fickian due to the homogeneity or heterogeneity of the porous medium conductivity layo…
The topological origin of anomalous transport: Persistence of β in the face of varying correlation length
Yaniv Edery
Traditional concepts for flow in porous media assume that the heterogeneous distribution of hydraulic conductivity is the source for the contaminant temporal and spatial heavy tail…
