Research Studentship in Combustor-Turbine Interactions
3.5-year D.Phil studentship, available from 11th October 2015 (subject to eligibility requirements below).
This studentship, fully funded by Mitsubishi Heavy Industries of Japan, is to investigate and unsteady interactions at the combustor-turbine interface in advanced gas turbines for power generation.
Gas turbine technology continues to play a major role in modern power generation. Impressive achievements have been made in recent years. For instance, the latest GTCC reaches efficiency of 61.5% and targets for temperature as well as efficiency are set even higher for the next generation gas turbine. This has been made possible by various core technologies such as employing advanced materials and sophisticated cooling strategies. The interface of combustor and high pressure (HP) turbine poses a major challenge but also a considerable opportunity for further improvements in performance. In the past, combustor and turbine have usually been developed separately and further improvements require a novel integrated approach. Recent research in Oxford has revealed an unsteady nature of aerothermal interactions at the combustor-turbine interface and suggests its implications on components’ life. This project will investigate experimentally and numerically the unsteady flow interactions at the combustor-turbine interface. A detailed measurement of turbulent flow inside the combustor transition duct and the downstream vane will be undertaken using hot-wires, hot-films and thin-films in a recently developed high-speed, experimental facility at the Osney Thermofluids Laboratory in Oxford. Numerical investigations will be performed using CFD and different advanced turbulence modelling strategies (LES, hybrid RANS-LES) in order to find ways to incorporate effect of these complex flow interactions into the existing design tools.
We are inviting candidates with excellent academic record, highly motivated and with excellent communication skills in English to apply. The successful applicant will join the Osney Thermofluids Laboratory and be supervised by Professor Budimir Rosic. Further information about the work of the group can be found at www.eng.ox.ac.uk/thermofluids
The studentship covers University and college fees plus a stipend (tax-free maintenance grant) of £14,400 p.a. for the first year, and at least this amount for a further two and a half years.
This studentship is available to all applicants UK/EU and Overseas.
Prospective candidates will be judged according to how well they meet the following criteria:
- A first class honours degree in Engineering;
- Strong academic background and interest in fluid mechanics;
- Experience with experimental fluid dynamics;
- Experience with Computational Fluid Dynamics;
- Excellent English written and spoken communication skills;
The following criteria are desirable but not essential:
- Experience in Labview and a CAD Package;
- Previous experience with hot-wire and hot-film CTA measuremens systems;
- Experience in basic turbomachinery principles;
To apply for this studentship, candidates should send the following documents to email@example.com:
- Covering letter (explaining your suitability for the study, what you hope to achieve from the DPhil and your research experience to date)
- Contact details for two academic or professional referees
NOTE: Candidates are expected to meet the graduate admissions criteria available at www.eng.ox.ac.uk/study-here/postgraduate/study-here/postgraduate/admissions-criteria and a full graduate application must be made at the same time as applying for this studentship. Your studentship application will not be considered until you have submitted a graduate application.
