Our paper—entitled “Coupled two-phase flow and surfactant/PFAS transport in porous media with angular pores: From pore-scale physics to Darcy-scale modeling“—is recently accepted for publication in the Advances in Water Resource Journal. The paper presents a modeling framework to translate interfacial phenomena and transport processes relevant to surfactant/PFAS from pore-scale into Darcy-scale. We provide a mechanistic tool to study the complex interactions between transient two-phase flow and surfactant/PFAS transport processes in diverse porous media. Example simulations highlight the critical role of pore angularity in PFAS transport and retention in unsaturated soils.
