Project description

First principles mathematical modelling, based on the use of direct numerical simulation coupled to Lagrangian particle tracking and interface tracking approaches, will be used to establish the fundamental particulate and carrier fluid properties that define the flow behaviour of slurries being transferred by continuous flow through pipes under a range of conditions. The aim is to provide basic understanding of these flows, and benchmark solutions that can be used to assess the accuracy of design tools that are more robust to wide ranging differences in plant conditions, composition and particle morphology than the current empirical techniques used in industry. In particular, behavioural modification techniques (such as the use of plasticisers, fluid pH and density changes, and responsive/smart fluids), which have been little used in industry, will be explored to establish how particle suspension, deposition and re-suspension behaviour in such flows can be tailored to meet operational requirements. As legacy retrievals and post operational clean out activities gather pace, therefore, opportunities will arise to intervene to improve flow, mixing and separation processes by the use of additives, or chemical or physical changes. The identification of suitable interventions, and the means to apply, control and evaluate their impact on wastes for disposal has the potential to accelerate decommissioning, and reduce secondary waste generation and plant size.

Entry requirements

Applications are invited from candidates with or expecting a minimum of a UK upper second class honours degree (2:1), and/or a Master's degree in a relevant engineering or science degree.

If English is not the applicant’s first language, they must provide evidence that you meet the University’s minimum English Language requirements.

How to apply

Formal applications for research degree study should be made on-line through the university's website. Please state clearly in the research information section that the PhD you wish to be considered for is 'Simulation of behavioural modification effects on multiphase pipe flows', as well as Professor Michael Fairweather as your proposed supervisor.

We welcome scholarship applications from all suitably-qualified candidates, but UK black and minority ethnic (BME) researchers are currently under-represented in our Postgraduate Research community, and we would therefore particularly encourage applications from UK BME candidates. All scholarships will be awarded on the basis of merit.

If you require any further information please contact the Graduate School Office, e:, t: +44 (0)113 343 8000.
