Bachelor theses / Master theses / Diploma theses / Compulsory internship

Chemical reactions fronts and instabilities comprise fields of research that constantly call for new challenges. Present in numerous technological applications (porous media, reactive mass transfer, CO2 capturing) they present diverse challenges. The potential intern/diplomand will be asked conduct experiments where a Xanthan Gum dispersion is injected into a surfactant (C14TAB) solution which is already inside a thin gap (Hele-Shaw cell) reactor. In this process, a weak gel membrane is formed by physicochemical interaction and a viscous instability emerges.

The candidate is expected to:

• Conduct experiments in the lab, using different chemical (e.g. concentrations) and hydrodynamic parameters (e.g. flow rate, flow cell).
• Image post-processing of the results and data analysis.
