PhD studentship in numerical modelling of carbon nanotube aerogel formation
Starting in October 2016 for 3.5 years.
UK and EU students only.
Individual carbon nanotubes (CNTs) have extremely high electrical conductivity, thermal conductivity, and yield strength. The engineering challenge is to create macroscopic CNT fibres that retain these extraordinary properties. A technique has been developed at Cambridge to form a cloud of interlocking CNTs, known as an aerogel, which can then be drawn out as a fibre. This works at low flowrates. The aim of this project is to model this numerically so that it can be designed to work at high flowrates.
This project will deal with three aspects of CNT fibre formation: (i) aerogel formation in a furnace, (ii) aerogel behaviour in the furnace, (iii) aerogel manipulation by the flow outside the furnace. Models will be developed in a finite element numerical platform. Sensitivities to model parameters will be calculated rapidly using adjoint methods. This will identify the most influential model parameters and inform experiments performed by another team, which will run in parallel with the modelling efforts.
The final stage of the project will be to use the numerical model and its sensitivities to iterate towards an optimal design of a CNT furnace.
Applicants should have an excellent academic track record in a scientific, mathematical, or engineering discipline. Some experience of object-oriented programming (e.g. Python) would be an advantage but is not essential.
Full funding, fees and Maintenance, is available only to UK and EU students. Overseas students are not eligible for this award.
