ERC project “TRACE-it” (2022-2027), summary:
Many engineering applications foreseen the usage of small particles for groundwater remediation or for sealing damaged geological confinement barriers, however, delivering materials to a contaminated or damaged region is challenging. TRACE-it aims at controlling the flow of colloidal particles in subsurface geological environments using in situ solute concentration gradients. The phenomenon, known as diffusiophoresis, has a tremendous potential to move colloids to regions that are inaccessible by conventional transport. Diffusiophoretic transport in porous media, however, has received very little attention so far. How to use concentration gradients of solute to transport colloids towards target regions? The team of TRACE-it project uses a combined experimental-modelling approach to tackle this challenge. More information here https: // erc-trace-it.cnrs.fr/
Role of the candidate
The objective is to develop a robust and validated macroscale model for particulate transport in porous media. The model will couple solute distributions predicted for subsurface processes (e.g. due to a contaminant dissolving in groundwater or due to mineral dissolution) and diffusiophoretic transport. The candidate will adopt a multi-scale strategy starting at the pore-scale before upscaling to the macro-scale. For that, the candidate will,
This work will allow the design of new remediation strategies to bring colloidal particles to contaminated areas in subsurface environments.
