DNAPL flow and complex electrical resistivity evolution in saturated porous media: A coupled numerical simulation

Geoelectrical and hydro-chemical monitoring of karst formation at the laboratory scale

“…In particular, geoelectrical methods are good candidates to detect the emergence of a sinkhole, to identify infiltration area, or to map ghost-rock features (e.g., Liñán Baena et al, 2009;Chalikakis et al, 2011;Meyerhoff et al, 2014;Kaufmann and Romanov, 2016) since they present a high sensitivity to physical and chemical properties of both porous matrix and interstitial fluids (e.g., Glover, 2015). An increasing amount of work has shown the interest and the effectiveness of geo-F. Rembert et al: Geoelectrical and hydro-chemical monitoring of karst formation electrical methods for laboratory or in situ monitoring of pore space description, hydrological processes, and contaminant transport (e.g., Revil et al, 2012;Garing et al, 2014;Jougnot et al, 2018;Ben Moshe et al, 2021;Sun et al, 2021;Koohbor et al, 2022). Studies on the geoelectrical monitoring of calcite precipitation and dissolution processes are emerging, highlighting their interest for non-intrusive characterizations (e.g., Wu et al, 2010;Zhang et al, 2012;Leroy et al, 2017;Cherubini et al, 2019;Niu and Zhang, 2019;Saneiyan et al, 2019Saneiyan et al, , 2021Izumoto et al, 2020Izumoto et al, , 2022Rembert et al, 2022a).…”

Microstructure Reconstruction and Gas-Liquid Two-Phase Transport Mechanism within Porous Electrodes of PEM Fuel Cells

“…In the field of energy and environment, the flow, heat, and mass transfer processes occurring in porous media generally exist [1,2], such as the migration and distribution of light non-aqueous phase liquid (LNAPL) [3] and heavy non-aqueous phase liquid (DNAPL) [4] in porous media soil, the heat and catalytic reaction process of porous media catalyst particles in chemical granular bed chemical reactors [5], gas-liquid electric thermal multiphysics simulation heat, and mass transfer process in fuel cell porous structure assembly [6][7][8]. The heat and mass transfer process in the above porous media is closely related to the energy and environment on which human beings rely for survival, and involves all aspects of human life and industrial generation.…”
