Mass transfer between recirculation and main flow zones: Is physically based parameterization possible?

JQ Zhou, L Wang, YF Chen… - Water Resources …, 2019 - Wiley Online Library
Recirculation zones (RZs) are common in many geophysical flows. These zones form near
irregular solid boundaries and are separate from the main flow. Since mass can be trapped …

Geometry‐based prediction of solute transport process in single 3D rock fractures under laminar flow regime

JQ Zhou, LG Guo, JJ Jiao, X Luo - Journal of Geophysical …, 2023 - Wiley Online Library
Subsurface substance migration in the fractured rock aquifer is mainly controlled by
fractures, and prediction of solute transport in fractures is important to many geophysical …

Effect of control domains of fractures and caves on reactive transport in porous media

X Su, N Qi, X Li, S Chen, L He - Physics of Fluids, 2023 - pubs.aip.org
It is often highly difficult to predict the main flow path of reactive fluids in porous media with
complexly distributed fractures and/or caves. Based on Darcy's law, this research defines the …
