Reactive transport modelling at pore scale is essential to improve fundamental understanding of chemical reactions in many applications including CO2 sequestration, petroleum engineering and spent nuclear waste disposal. With the development of computers and X-ray tomographic imaging techniques that provide detailed information of pore structures, pore-scale direct numerical simulation of flow and transport in porous media has become increasinly popular. In this talk, I will present our pore-scale studies on reactive low and transport phenomena, including pore structure and mineralogical heterogeneity during acid injection in petroleum engineering, grain detachment and migration of CO2 sequestration and corrosion of uranium dioxide in a geological repository. Pore-scale direct modelling is shown to be a potentially powerful numerical tool to analyze reactive flow and transport processes in various energy and environmental systems.
Min Liu obtained his Ph.D. in Petroleum Engineering from the University of New South Wales (UNSW), Australia (2017). After graduating from UNSW, he was awarded a Writing Fellowship and continued working in Australia until joining Oak Ridge National Lab as a postdoc research associate in 2018. Currently, he is a research associate at the Los Alamos National Lab. His research interests include reactive transport, modelling of fluid flow in porous media with applications to oil and gas recovery, subsurface hydrology, nuclear waste disposal and environmental studies.
