About the Project
We believe we have found that there are two new mechanisms for heat transfer in nanofluids (see Ref. ) which may explain the difficulties experienced in measuring and predicting the thermal conductivity of nanofluids. Our recent letter  is a study of simple/theoretical gas mixtures where we demonstrated that new unusual heat-transfer phenomena might exist in gas mixtures, such as super-conducting and super-insulating heat effects. To investigate these effects we are now turning to experimental studies. We’ve recently constructed a Transient Heated Wire test cell. This device is unique as it can conduct heat transfer measurements on gases at the timescale of microseconds and measure temperature changes in the order of millikelvin. This will be used to investigate thermal conductivity of mixtures and also new physical phenomena such as time-dependent effects.
The project here is to continue our experimental, theoretical, and computational work in this area. The student will be trained in each of these techniques and will be able to focus on the areas that play to their individual strengths. Computational fluid dynamics simulations, coupled with kinetic theory, will be used to design new nanodevices that exploit these effects. Experimental work on the Transient Heated Wire apparatus will attempt to prove the existence of the effects in real fluids and measure their magnitude. Molecular dynamics techniques are also available to simulate heat transfer at the nanoscale and to validate theoretical ideas for the nanofluid heat transfer mechanisms. There is scope for the student to construct their own scientific instruments which is a common activity within our group, as well as work with regional universities collaboratively on this project.
Candidates should have (or expect to achieve) a UK honours degree at 2.1 or above (or equivalent) in Chemical Engineering, physics, chemistry or a related field.
Any background in molecular dynamics, computational fluid dynamics, or experimental work in the area of heat transfer is highly desirable.
