Pore-scale modeling of complex transport phenomena in porous media
TL;DR: Pore-scale modeling is an efficient tool for the simulation of porescale 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 as discussed by the authors .
