Due to unique properties of supercritical CO2 (sCO2), sCO2 gas turbines have many advantages over their counterparts, such as being more compact, lower costs, using single-phase fluid rather than two-phase fluid compared with steam turbines, higher cycle efficiency when using low temperature heat sources compared with gas turbines, etc. The aim of this PhD research is to develop novel performance simulation, optimization, and diagnostic methods for sCO2 gas turbines. The new knowledge will assist performance designs, analysis, operations, and condition monitoring of sCO2 gas turbines.  The studentship offers partial funding to the student for three years.

Cranfield has developed a unique methodology and software to simulate and analyse the performance of gas turbine engines. The research in this area at Cranfield will be a good starting point for the proposed project.  The focus of the research is to extend the existing performance and diagnostic capabilities to supercritical CO2 (sCO2) gas turbines for power generation or marine applications. The critical components of sCO2 gas turbines, such as heat exchanger, compressors, turbines, condenser, and the whole system integration will be simulated thermodynamically. Performance design optimization and gas path diagnostic methods will be investigated and corresponding computer software will be developed. The research will contribute to the development of digital twin technologies for sCO2 gas turbines.

The Centre for Propulsion and Thermal Power Engineering has a key focus and a proven track record on gas turbine performance, gas path diagnostics, novel thermodynamic cycle performance, etc., which have been built up over the last half century. This provides a unique capability to assist researchers and engineers in new engine and power plant designs and support the users in optimizing the profits of gas turbine and power plant operations, improving power system availability and reducing maintenance costs.

Cranfield operates a substantial Doctoral Researchers Core Development programme (DRCD) for its research students. This programme provides a generic structured training programme which is constructed to support the researcher as the PhD progresses with specific courses aimed at the different phases of a PhD. For example, the programme includes aspects such as research methods, technical report writing, presentation skills, data management, leadership skills, professional development planning, intellectual property, publishing, etc. Such knowledge, skills and capability will enhance the student's employment opportunities in both academic institutions and industry.

This is an exciting opportunity for a suitable candidate where he or she will be exposed to the latest technology, learn from experts working in the area and prepare for an exciting career in either academia or industry.

Entry requirements

Applicants should have a first or second-class UK honours degree in mechanical engineering or a relevant area. An MSc degree or experience in thermodynamics, gas turbine technology, and computer programming will be an advantage.    

Funding

Partial funding for bursary is available for both UK and non-UK candidates and the amount will depend on the background of the candidate.
