Understanding particle transport behaviors in porous media during multiphase flow is crucial for a wide range of applications in environmental engineering, energy recovery, and materials science. This paper provides a comprehensive overview of recent advances in experimental techniques, mechanistic studies, and modeling approaches related to particle transport under multiphase flow conditions. We first review recent progress in experimental platforms and imaging techniques that enable visualization and quantification of particle dynamics in porous media. Subsequently, key transport mechanisms, including attachment and detachment, straining, size exclusion, and aggregation, are systematically revisited, along with the influence of various physicochemical conditions. Special attention is given to the coupling between particles and deformable interfaces in, e.g., bubbles, droplets, and thin films. Furthermore, we examine recent developments in numerical modeling approaches for particle transport and multiphase flow. Knowledge gaps in particle transport mechanisms during multiphase flow and challenges associated with multiscale modeling are also outlined. This review can provide a unified framework for understanding and predicting particle transport in porous media under multiphase flow conditions, and guiding future research on interface-mediated particle manipulation and transport control.

Pore Transport and Ion-Pair Transport
Pore transport, also known as convective transport, is a process where small molecules like urea, water, and sugars rapidly cross cell membranes as though there were channels or pores in the membrane. Although direct microscopic evidence is limited but the concept of pores or channels is widely accepted based on physiological evidence. Despite the lack of direct microscopic...
