Abstract

This review summarizes the recent advances and challenges in pore-scale modeling, discussing its practical applications in geoscience, polymer exchange membrane fuel cells, and solid oxide fuel cells. Notable results from pore-scale modeling are presented, while the challenges facing the development of pore-scale models are also discussed.

Porous media play important roles in a wide range of scientific and engineering problems. Recently, with their increasing application in energy conversion and storage devices, such as fuel cells, batteries and supercapacitors, it has been realized that transport processes and reactions occurring in the pores and at the interfaces of different constituents significantly affect the performance of the porous media, yet these pore-scale transport phenomena are not well described or even neglected in the conventional numerical models based on the representative element volume (REV). Pore-scale modeling is an efficient tool for the simulation of pore-scale transport and reactions in porous media because of its ability to accurately characterize these processes and to provide the distribution details of important variables which are challenging for current experimental techniques to provide either due to lack of in-situ measurement capability or due to the limited spatial and temporal resolution. In the present review, the advances and challenges of the state-of-the-art pore-scale modeling are summarized. The practical applications of pore-scale modeling in the fields of geoscience, polymer exchange membrane fuel cells (PEMFC) and solid oxide fuel cells (SOFC) are discussed. Notable results from the pore-scale modeling are presented, and the challenges facing the pore-scale model development are discussed. This in-depth review is intended to give a well-rounded introduction of critical aspects on which the pore-scale modeling can shed light in the development of relevant scientific and engineering systems.

Summary: This article discusses the role of multiphase flow and reactive transport in geological carbon sequestration and introduces the methods of pore-scale simulation and continuum modeling. It elaborates on four sequential mechanisms of CO2-brine-rock interaction and presents the risks of leakage during carbon sequestration and CO2-enhanced oil recovery. The challenges and future directions in pore-scale modeling and the field of carbon sequestration are also discussed. This review is expected to be beneficial for researchers interested in pore-scale simulations, carbon sequestration, and related disciplines.
