Development of supercritical CO2 based waste heat recovery system

This 3.5-year university funded PhD studentship aims to develop a supercritical CO2 cycle based waste heat recovery system.

Start date

1 October 2022


3.5 years

Application deadline

Funding source

University of Surrey

Funding information

The studentship will cover UK-based University fees and a stipend (£15,400) for 3.5 years in addition to £1,000 per annum to be spent on research and training for the student.

For an international student, the studentship will cover an international tuition fee.


Supercritical CO2 based waste heat or low grade heat recovery system is a key technology to improve system efficiency thus contributing to the NetZero target. This project aims to develop the system and key components such as expander, compressor and heat exchangers by numerical modelling, supported by experimental testing. Advanced simulation approach such as liquid-solid coupled simulation and potentially Direct Numerical Simulation will be employed to develop the numerical models which will be used to optimise the design and evaluate the performance. With support from other team members, the candidate will also improve an existing test bench to conduct experimental investigation of the key components in the system. The test results will be used to calibrate and validate the numerical models that are developed in this project.

The candidate will collaborate with other researchers in the group with international background. Short to mid-term exchange opportunities in overseas institutes will also be offered to the candidate.

Eligibility criteria

Open to UK and international applicants. Applicants are expected to hold a first or upper-second class degree in a relevant discipline (or equivalent overseas qualification), or a lower second plus a good Masters degree (distinction normally required).

If English is not the first language, IELTS 6.5 or above (or equivalent) is required, with no sub-test score less than 6.

How to apply
