EPSRC DLA Studentship - Particle-driven convection in a stratification: The mystery of ocean plastics

Ocean plastics harm marine life, the environment and human health. Although we know that large amounts of plastics are entering the oceans, our measurements of the concentration of plastic particulates in the ocean are much lower than we would expect. This research will help to answer this mystery, by investigating how particles settle in a stratified ocean.

This project will use laboratory experiments to investigate particle-driven convection, which occurs when particles settle through a stably stratified interface. Even though the initial stratification is stable, particle settling leads to an unstable interface in the density field, driving an instability. Using experimental techniques, such as PIV and PTV, shadowgraph imaging and dye attenuation, experiments will be used to characterise the flow and develop an understanding of the important physics.

The results of this research will also have a wider impact as particle settling in a stratified environment is significant for a wide array of geophysical flows, from cloud formation (a key unknown in climate models) to ash-settling from volcanic eruptions.

EPSRC DLA studentships are fully-funded (fees and maintenance) for students eligible for Home fees. EU and international students may be considered for a small number of awards at the Home fees rate. Full eligibility criteria can be found via the following link; ?url=https%3A%2F%2Fwww.postgraduate.study.cam.ac.uk%2Ffinance%2Ffees%2Fwhat-my-fee-status&module=jobs&id=261465" target="_blank" rel="nofollow">?url=https%3A%2F%2Fwww.postgraduate.study.cam.ac.uk%2Ffinance%2Ffees%2Fwhat-my-fee-status&module=jobs&id=261465" target="_blank" rel="nofollow">https://www.postgraduate.study.cam.ac.uk/­finance/fees/­what-my-fee-status .

Applicants should have (or expect to obtain by the start date) at least a good 2.1 degree in an Engineering or related subject.

The candidate will need a strong theoretical background in fluid mechanics, along with experience of practical/experimental research projects and good programming abilities (e.g. Matlab, Python).

Applications should be submitted via the University of Cambridge Applicant Portal ?url=www.graduate.study.cam.ac.uk%2Fcourses%2Fdirectory%2Fegegpdpeg&module=jobs&id=261465" target="_blank" rel="nofollow">?url=www.graduate.study.cam.ac.uk%2Fcourses%2Fdirectory%2Fegegpdpeg&module=jobs&id=261465" target="_blank" rel="nofollow">www.graduate.study.cam.ac.uk/courses/­directory/egegpdpeg , with Megan Davies Wykes identified as the potential supervisor.

The funding is conditional on submitting this application before 31 March 2025.

The University actively supports equality, diversity and inclusion and encourages applications from all sections of society.
