Mathematical modelling of chemical transport in a porous medium with evolving microstructure

This project is a full-time 4-year structured PhD project based in the Mathematics Applications Consortium for Science and Industry (MACSI) in the University of Limerick. The funding includes a tax-free stipend (with fees paid) along with expenses for computing equipment, conference travel and materials.

The research topic is mathematical analysis of porous systems with an evolving microstructure. Dissolving tablets, brewing coffee and battery operation all require transport of chemicals through liquid-filled porous structures. Transport across these systems is strongly dependent on microstructural properties (e.g., porosity, tortuosity, permeability), and often these properties change during interactions between the solid, liquid, and dissolved chemicals.

In this project, perturbation methods (also known as asymptotic analysis) will be developed for accurately modelling macroscale dynamics in structured porous media. The candidate will learn to use mathematical homogenization to systematically account for an evolving microstructure and link microscale phenomena to macroscale behaviour. The derived models will be deterministic in nature and will be analysed and solved using a combination of dimensional analysis, asymptotic methods, and numerical techniques. The methodology will be applied to extend models of drug release from tablets, gels, and stents to include biodegradation, with the goal of facilitating the understanding and control of such systems. Wider applications include coffee brewing, battery technology and contaminant transport.
