Non-invasive imaging of REV-scale experiments to understand how fluid-solid reactions affect flow and transport in porous media (C05)

• Subject Area: Hydrogeology, Hydrology, Limnology, Urban Water Management, Water Chemistry, Integrated Water Resources Management ; Applied Mechanics, Statics and Dynamics ; Mechanics
• Term: since 2018
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 327154368

The aim of this project is to experimentally investigate how reactions at the fluid-solid interface affect flow, transport and deformation in porous media. For this, we will use REV-scale experiments combined with non-invasive imaging techniques (X-ray computed tomography, time-lapse imaging with digital cameras) to investigate how salt precipitation during evaporation of saline water from porous media affects evaporation, sample deformation, as well as desiccation cracking.
