Heat transfer in liquid spraying systems

Applications are invited for a full time PhD scholarship funded by Brunel University London. The studentship is for a period of 3 years starting in January 2024.

The successful applicant will receive an annual stipend of £20,662 plus payment of their full-time home tuition fees. This 3-year fully funded scholarship is only open to UK home students.

Project Details

The project is in an exciting field at the forefront of research in spray cooling techniques for high heat flux applications. It involves advanced fundamental experimental heat transfer research. The successful candidate will be based at Brunel University London, but will be part of a team working with academics and researchers at Imperial College London, the University of Edinburgh and industrial partners.

The research carried out by the successful applicant will start with the setting up of an experimental facility, followed by a systematic study of single and two-phase spray cooling. The project will include an assessment of the effect of fluid properties, spray nozzle diameter, height-surface area ratio, volume flow rate and surface characteristics on possible heat transfer rates from the area to be cooled. The heat flux to be dissipated and the degree of superheat (difference between the surface and the spray fluid temperature) will be gradually increased to study transition from single-phase to two-phase heat transfer in the area covered by the spray. Flow visualization experiments will also be carried out with high-speed, high resolution cameras. Our results will be compared with the experimental and modelling results obtained by Imperial and Edinburgh.

Eligibility

Applicants will have or expect to receive a first degree at 2:1 or above in an Engineering or Physical Sciences related discipline. A Master’s degree is an advantage but not essential. Applicants with a Mechanical, Aerospace and Chemical Engineering background having taken relevant courses in thermofluids are strongly encouraged to apply.
