Fluid-solid reactions pose a challenge for modelling flow and transport in porous media due to the dynamic changes in the pore space and the associated alteration of the permeability. The aim of this project is to experimentally investigate how reactions at the fluid-solid interface affect flow and transport in porous media. For this, we will use REV-scale experiments combined with non-invasive imaging techniques (X-ray computed tomography, unilateral nuclear magnetic resonance, and magnetic resonance imaging measurements) for two different reaction systems: salt precipitation during evaporation and microbially-induced calcite precipitation.
