Contact line dynamics and healing liquid films

One of the more challenging aspects of modelling fluid dynamics is the contact-line problem: how does a contact line (a junction between two different fluids and a solid) move over time? A variety of models exist, such as disjoining pressure models, Navier slip models, and the imposition of a prewetting film, to name a few.In this project we will explore the behaviour of these different contact line models in the context of closing or healing liquid films. A hole in …

Modelling convection in porous media

When liquids of different densities mix, they can produce complex fingering patterns. This is particularly important in the flow of liquid in underground porous aquifers, where the density of the groundwater can be influenced by salinity or heat, as well as the insulation properties of porous materials. Another important application is the still-prototypical use of aquifers for carbon sequestration; the dissolution of CO2 into groundwater has a complex effect on its density, and convective mixing is crucial for accelerating the …
