The focus of my research is porous media flows with moving interfaces separating different phases at the pore scale. I am part of the DynScale project.
Groundwater remediation, oil recovery from reservoirs, CO2 sequestration, the dissolution/precipitation of minerals are applications of flow (single or multiphase) and (reactive) transport processes trough porous media. These applications are huge and omnipresent. The ongoing research not only contributes significantly to the problems on a large scale (e.g. groundwater, oil reservoir) but also addresses to the problems at the micro scales (e.g. biological cell membranes, biofilms).
The flow and transport processes take place at the micro scale involving complex microstructures. This complexity makes the mathematical and numerical analysis of such processes very difficult at the micro scale. Since the last decade, upscaling of such processes from a micro to a macro scale is a common practice among researchers. The goal of my research is to find effective (upscaled) models, which are not only less complex to describe, but also very efficient to simulate.
