Functie omschrijving

In the Physics of Complex Fluids group at the University of Twente (Enschede, The Netherlands), research is aimed at understanding various behaviors of multi-component fluids near interfaces. In the cCOOL project we develop the permanent storage of CO2 inside clay materials underground as a negative emission technology. In this collaborative project (involving 4 temporary researchers), the CO2 loading and storage is addressed at the level of the individual clay particles as well as the collective mechanical and chemical behavior at rest and in flow. 

Aim is to find the conditions under which the CO2-loaded clay material can be stored most efficiently in the pore space of geological rock. To facilitate their transport, the clay particles will be suspended in aqueous liquid. A key challenge will be to achieve a high packing density in the end, while avoiding flow obstructions in the pathway. This optimization requires a (sodar lacking) understanding of the rheology of the clay suspension(s) in microchannel geometries. Particle interactions, concentration, flow rate and pore geometry are all expected to play a role. Their influences will be examined via bulk rheology, and microscopic visualization of the flow and clogging behavior inside microchannels. The achieved dense state in which the clay gets stored will also be examined for the time dependence of its rheological properties and its CO2-content.
