Boiling is a common but fundamental phenomena required in modern manufacturing equipment. Typically, boiling begins with nucleation on a heated surface. However, most of these surfaces are not design efficient, and are sub-optimal leading to energy loss. We have recently secured funding from the EPSRC to develop Enhanced Multiscale BOiling SurfaceS (EMBOSS)
This fully funded (for UK or EU)* PhD project will tackle modelling of mesoscale and macro scale aspects of bubble growth during boiling - using lattice Boltzmann, direct numerical simulations (CFD/ DNS) methods and theory. The potential student will collaborate closely with molecular dynamics modeller at Imperial College London and experimentalists at Brunel University London and The University of Edinburgh.
The goal of the modelling is to:
- Further our current understanding of boiling, in particular, the principles that govern bubble growth beyond the nucleation stage.
- Unravel the physics underlying the phenomenon – including how the bubble departs from the surface.
- Check how these underlying principles scale with bubble populations and what are the mechanisms involved.
This project contributes towards the development of a multiscale modelling framework, to not only answer the above questions, but also to help design optimal surfaces for maximum heat transfer and energy efficiency.
This PhD position offers an excellent opportunity for further career development.
- Institutional and Peer Support: The potential student will benefit from excellent supportive environment at the School of Engineering within the Institute for Multiscale Thermofluids at The University of Edinburgh.
- Industrial Collaboration: The student will also interact closely with our industrial collaborators including Thermacore Europe, Alfa Laval, CALGAVIN, Oxford Nanosystems, Intrinsiq Materials, TMD Ltd, and Oxford Lasers.
- International Secondments: This PhD also comes with an opportunity to conduct secondments with our partners under the ThermaSMART consortium (funded by the European Commission) either at University of Maryland USA, York University Toronto Canada or at Kyushu University Japan. This fully funded secondment (for around 6 months) will involve the student performing targeted experiments at world-class facilities at our partners.
- Impactful publications and dissemination: The student will also benefit from strong support towards publications in premier journals (including the Journal of Fluid Mechanics and Physical Review Fluids) and participation in major conferences (including the American Physical Society – Division of Fluid Dynamics Meetings and the International Heat Transfer Conference).
* International students with their own scholarships (such as from their governments) are most welcome to apply but if selected an international student can only be awarded tuition fees at the Home/EU rate (and stipend). Funding must therefore be secured to cover the difference between Home/EU rate and the International rate.
