- Qualification Type: PhD
- Hours: Full Time
- Title of project: Experimental characterisation of high-speed two-phase expansion for power generation
- Placed On: 1st March 2022
- Closes: 15th May 2022, or until places have been filled.
Overview
Applications are invited for a PhD studentship in the Department of Engineering. The successful candidate will have the opportunity to work on the design and commissioning of a lab-scale test loop to investigate the two-phase expansion of organic fluids.
The topic is of relevance to novel low-temperature power generation systems, which are suitable for applications such as geothermal, solar-thermal, and biomass applications alongside waste-heat recovery.
Of particular interest is two-phase expansion within organic Rankine cycle (ORC) systems which could lead to up to a 30% increase in performance compared to conventional ORC systems.
This project forms part of on-going research within the group focussing on the design of turbomachinery components for two-phase expansion.
Specifically, the focus is on the use of molecularly complex working fluids with conventional turboexpanders which could permit an expansion from two-phase conditions to be confined within the stator of the turbine and end in the dry-gas region.
The aim of this project will be to design and commission a new experimental test loop to experimentally examine two-phase expansion under operating conditions relevant to future power energy technologies, and to provide experimental data for validation of numerical models.
A closed-loop test facility will be developed to investigate the expansion of a two-phase mixture within relevant turbomachinery geometries.
The proposed research will afford the student a chance to explore fundamental features of high-speed two-phase flows of non-ideal fluids. These skills are expected to be sought after highly by industry and can also provide a robust foundation for an academic career.
The results of a successful doctoral thesis are expected to be of interest to emerging power generation industries which can help to provide clean, sustainable, and secure energy and meet 2050 net-zero targets.
The student will be encouraged to publish results of their research at leading international conferences and in top-tier journals. They will also be encouraged to communicate directly with potential industrial partners.
Eligibility and requirements
The candidate should have an upper second-class BSc/BEng/MEng (or equivalent, or higher) degree in Mechanical, Aeronautical or Energy Engineering, or a closely related field. They should also demonstrate an aptitude for conducting original research.
The candidate should possess a good understanding of thermodynamics, fluid mechanics and aerodynamics, preferably within the context of power generation applications and turbomachinery. Experience in experimental design and in experimental aerodynamics will be advantageous.
A candidate who demonstrates exceptional aptitude in one or more of these areas (as evidenced, for instance, through strong academic credentials or research papers in reputable, peer-reviewed journals/conferences) may be accorded preference.
A doctoral candidate is expected to meet the following pre-requisites for their PhD:
- Demonstrate a sound knowledge of their research area
- Achieve and demonstrate significant depth in at least a few chosen sub-areas relevant to their primary research area
- Demonstrate the ability to conduct independent research, including a critical assessment of their own and others’ research
Having published high-quality papers in reputable peer-reviewed conferences and journals will be an advantage for the candidate.
Funding
The studentship is for 3 years and will provide full coverage of tuition fees (Home and Overseas) and an annual tax-free stipend of £12,000.
Each student would also have the opportunity to earn around £2.2K pa on an average (max. is around £4.3K pa) through a teaching assistantship. We shall prioritise these scholarship holders while allocating the teaching assistantships.
How to apply
If you are interested in applying, you are encouraged to email initial informal enquiries to Dr Martin White.
Visit our Mechanical Engineering and Aeronautics research degrees web page for further information on making a formal application.
When submitting your application, enter the title “Experimental characterisation of high-speed two-phase expansion for power generation” and you will automatically be considered for this studentship.
You do not need to submit a proposal as part of your application as the project has already been outlined.
The online application can be found in the ‘How to apply section’ in the web link above and should include the following supporting documents:
- Copies of Degree Certificates and Transcripts in official English translation - original will be requested before an offer is made.
- Official work e-mail addresses (not private ones) for two referees (one of which must be an academic).
- Proof of English Language proficiency (minimum average score of 6.5 IELTS, with a minimum of 6.0 in each of the four components) if English is not your first language.
- Passport.
The outcome of the selection process should be announced by the end of June. The successful candidate will formally start their doctorate either in July or in October 2022.
