PhD Studentship: Heat Transfer Effect on Nonlinear Disturbances in Transitional Boundary Layers
Location: Sheffield | Funding for UK Students | Full Time
Placed On: 6th May 2026 | Closes: 5th August 2026
About the Project
An exciting PhD project on the effects of heat transfer of transitional compressible boundary layers will be carried out under the UK Hypersonics Doctoral Network, which has been supported by the Ministry of Defence and EPSRC for building the necessary expertise to develop next-generation hypersonic vehicles. This offers a fully funded 4 years stipend and tuition fees at the Home status rate at the School of Mechanical, Aerospace and Civil Engineering at the [Employer hidden — sign up to reveal] under the supervision of Professor Pierre Ricco (www.pierre-ricco.co.uk). Additionally, the student will be expected to attend cohorting and training activities in the UK Hypersonics Doctoral Network, led by the University of Oxford and Imperial College. Each Cohort will have at least 8 students studying across a number of UK Universities.
Students recruited must be citizens of one of the 'AUKUS' alliance nations (United Kingdom, Australia and the United States of America), and should not have dual nationality with any country on the UK Government's list of countries subject to trade sanctions, arms embargoes and other trade restrictions (www.gov.uk/guidance). The award will cover the Home fees only.
Topic of Research
The laminar-turbulent transition in boundary layers is one of the most challenging topics in classical physics and applied mathematics, and stands as a bottleneck problem in the modern flow engineering technology. It is desirable to predict the occurrence of transition to turbulence and suppress the unstable disturbances in boundary layers that lead to transition because the increase of wall friction and wall-heat transfer are major issues in turbulent-flow conditions. The central objective of the project is to utilise wall cooling/heating to stabilise the boundary layer and obtain a delay of transition to turbulence. The methodology of the research is theoretical and numerical, i.e. an existing in-house code will have to be modified. This project offers the unique opportunity to develop strong skills in viscous fluid mechanics, numerical methods and applied mathematics.
Start date: October 2026. Duration: 4 years.
