Numerical simulations of NMR relaxation in chalk using local Robin boundary conditions
M. Ogren, D. Jha, S. Dobberschutz +5
The interpretation of nuclear magnetic resonance (NMR) data is of interest in a number of fields. In Ögren [Eur. Phys. J. B (2014) 87: 255] local boundary conditions for random wal…
Momentary increase in reactive surface area in dissolving carbonate
Y. Yang, M. Rogowska, Y. Zheng +4
The quantification of surface area between mineral and reactive fluid is essential in environmental applications of reactive transport modelling. This quantity evolves with microst…
Retraction of dissolution front in natural porous media
Yi Yang, Stefan Bruns, Melania Rogowska +4
The dissolution of porous materials in a flow field shapes the morphologies of many geologic landscapes. Identifying the dissolution front, the interface between the reactive and t…
Direct observation of coupled geochemical and geomechanical impacts on chalk microstructural evolution under elevated CO2 pressure. Part I
Y. Yang, S. S. Hakim, S. Bruns +5
The dissolution of porous media in a geologic formation induced by the injection of massive amounts of CO2 can undermine the mechanical stability of the formation structure before…
Path selection during wormhole growth
Y. Yang, S. S. Hakim, S. Bruns +4
Growth of wormholes in porous media can lead to self-organization of flow networks with an overwhelming geometric complexity. Despite decades of study, the mechanism by which a dom…
