The EPSRC Centre for Doctoral Training in Fluid Dynamics is now recruiting to this fantastic PhD opportunity in partnership with Sellafield Ltd.
As a student on the CDT you will participate in a four year programme that combines an integrated MSc (completed over the first two years) paired with a three year PhD-level research programme. This gives you a combination of bespoke taught modules and inter-disciplinary research training.
You will be part of a supportive cohort of research students with different academic backgrounds, all focusing on different aspects of Fluid Dynamics. During the taught aspects of your course you will receive a range of tailored seminars, lectures and practical laboratories to cover the computational, experimental and analytical aspects of Fluid Dynamics. This provides you with a strong background to the fundamentals of Fluid Dynamics. In addition you will have access to a wide range of personal development activities. Further information on the CDT is available here: fluid-dynamics.leeds.ac.uk
The PhD project: Bubble growth and gaseous release dynamics within viscoelastic soft sediments
The growth, retention and release of trapped gas within soft sediments is critically important in many natural and engineered systems; from methane formation within the muddy beds of aquatic reservoirs and waste water sludges to safety concerns from flammable gas release in corroded legacy metallic wastes. This project will seek to significantly enhance our knowledge of these systems, by examining the mechanisms of bubble growth and release in viscoelastic sediments. In particular, we will focus on characterising the interplay between sediment microstructure (e.g. porosity) and fluid rheology on the dynamics of initial single bubble growth, secondary formation of interconnected bubble networks and the resulting influence on continuous gaseous release. The project will combine state-of-the-art x-ray CT measurements and visual data analysis with Lattice-Boltzmann and Monte Carlo techniques to simulate gas flow through porous networks as well as analytical modelling to link sediment rheology to bubble growth dynamics. The project is a collaboration with Sellafield Ltd., the U.Ks largest nuclear operator, with work focused on assessing hydrogen release in nuclear wastes, however, outcomes are transferrable across natural sedimentology, particle engineering and complex fluid sciences.
