Research topic Gas Turbine Aerothermal Performance Principal Investigator / supervisor Dr Paul Beard Project team Oxford Turbine Research Facility Project web site www.ox.ac.uk/ & http://oti.eng.ox.ac.uk/ Funding partner The funds supporting this research project are provided by RollsRoyce plc Recent publications Falsetti, C., Beard, P., Cardwell, D., & Chana, K. (2022). A Review of High-Speed Rotating HP Turbine Heat Transfer and Cooling Studies Over the Last Decade in the Oxford Turbine Research Facility. GT2022-81945. Proceedings of ASME Turbo Expo 2022, Rotterdam. doi.org/10.1115/ GT2022-81945 The role The Oxford Thermofluids Institute at the Department of Engineering Science, Oxford University has a strong and long-standing research collaboration with Rolls-Royce plc, one of the global leaders in jet-engine design and manufacture. Over the past few years, the Institute has significantly expanded its high TRL (test readiness level) capability, with the Oxford Turbine Research Facility (OTRF) being central in this strategy. For decades, the OTRF was operated as a short test duration facility with a long-proven track record and extensive capability to deliver world-leading aerodynamic and heat transfer measurements. Previously known as the Turbine Test Facility (TTF) at QinetiQ, the facility was relocated to the University of Oxford in 2011. Following a significant infrastructure upgrade to the facility over 2019-2023, the facility run time has been increased from from 0.5s to 60s, enabling metal effectiveness (non-dimensional metal surface temperature) and cooling effectiveness measurements at non-dimensional engine conditions. Measurements are performed using a novel infrared measurement system capable of acquiring full surface temperature maps of any high-pressure turbine rotor blade under test. An innovative approach to turbine blade manufacture, involving rapid and agile metal sintering, has also been developed to allow flexible manufacture of novel turbine blade variants suitable for scaled testing in the OTRF. Together these advances facilitate high TRL aerothermal testing of multiple component designs in a single rotor assembly, and ultimately, ranking of multiple cooling technologies on rotating turbine components prior to a multi-million-pound engine test by an engine provider, such as Rolls-Royce. Recent research projects have included studies of effusion cooling on the rotor casing, turbine blade squealer tip design, cooled rotor blade heat transfer, combustor-turbine interactions with lean burn and entropy noise generation in the turbine. Projects have been funded by RollsRoyce plc, Innovate UK, the EU Framework programmes and GKN Aerospace. A review of the last decade of research in the Oxford Turbine Research Facility was recently presented by Falsetti et al. 2022. A copy of this paper can be provided on request if need be. Falsetti, C., Beard, P., Cardwell, D., & Chana, K. (2022). A Review of High-Speed Rotating HP Turbine Heat Transfer and Cooling Studies Over the Last Decade in the Oxford Turbine Research Facility. GT2022-81945. Proceedings of ASME Turbo Expo 2022, Rotterdam. doi.org/10.1115/ GT2022-81945. Based at the Oxford Thermofluids Laboratory (Osney Mead, Oxford) the successful candidate will be responsible (as part of the OTRF team) for the aerothermal design, manufacture and testing of multiple cooled turbine components for the testing in the upgraded test facility. This will involve working closely with experts at Rolls-Royce plc in Derby.

The course is accredited at MEng level by the major engineering institutions. The syllabus has a common core extending through the first two years. Specialist options are introduced in the third year, and the fourth year includes further specialist material and a major project. Research Research in the Department is particularly strong. We have approximately 600 research students and about 250 postdoctoral researchers. Direct funding of research grants and contracts, from a variety of sources, amounts to an annual turnover of approximately £70m. The results of the seven-yearly UK-wide assessment of university research, REF2021, published on 12th May 2022, demonstrate that the University of Oxford made the highest volume of world-leading research submissions. The Department of Engineering Science had 71% of submissions which met the requirements for the highest grading of 4*(research that is world-leading in terms of originality, significance, and rigour). Research activities fall into 8 broad headings, though there is much overlapping in practice: Information Engineering (Robotics, Computer Vision and Machine Learning); Control; Thermofluids; Materials and Mechanics; Civil and Offshore; Electrical and Optoelectronic; Chemical and Process; and Biomedical.
