Effect of poroelastic coupling and fracture dynamics on solute transport and geomechanical stability

M Tran, B Jha - Water Resources Research, 2021 - Wiley Online Library
The coupling between solute transport and rock's geomechanical processes, for example,
flow‐induced fracture activation, has emerged as an important hydrogeological challenge …

Solutal convection in porous media: Comparison between boundary conditions of constant concentration and constant flux

MA Amooie, MR Soltanian, J Moortgat - Physical Review E, 2018 - APS
We numerically examine solutal convection in porous media, driven by the dissolution of
