With a growing interest in the introduction of hydrogen to the natural gas grid, and its resultant use, including pure hydrogen, in homes for heating, cooking and power supply it is important to understand the specific hazards and associated risks pertinent to the use of hydrogen in a domestic setting. Appliances such as fuel cells, boilers, and burners, are being developed specifically for use with hydrogen and hydrogen blends.
Validated contemporary CFD models and reduced engineering tools for reliable prediction of an incident dynamics in a residential setting are needed for reliable hydrogen safety engineering. Safety challenges include understanding the behaviour of a leak of hydrogen or hydrogen blends, including harmful impurities, validation of the similarity law for concentration decay in momentum-dominated jets for blends, application of the under-expanded jet theory to blends, assessment of leak and dispersion of flammable gas from flanges and joints, safety strategies to exclude accumulation of flammable mixtures, and appropriate venting strategies.
The effect of buoyancy on the release of hydrogen blends could also be investigated. Hydrogen specific prevention and mitigation concepts are needed to efficiently tackle hydrogen dispersion and combustion in residential environments. There is a need to understand and exclude the potential thermal and pressure effects of an incident on the integrity of the property.
This doctoral study could incorporate elements of the following:
The expected impact of the study could include: validated contemporary CFD models and engineering tools for hydrogen safety engineering; deeper knowledge of the underlying physical phenomena; innovative prevention and mitigation strategies; guidelines for inherently safer design and use of hydrogen in a domestic setting, etc. The study will focus on a combination of theoretical and numerical (CFD) studies, the use of ANSYS Fluent as a computational engine, multi-processor Linux-based hardware of HPC suite, etc. The results of this doctoral research will be aligned to HySAFER’s externally funded projects and reported at international conferences as relevant.
Publication of results in peer-reviewed journals is expected.
Applicants should hold, or expect to obtain, a First or Upper Second Class Honours Degree in a subject relevant to the proposed area of study.
We may also consider applications from those who hold equivalent qualifications, for example, a Lower Second Class Honours Degree plus a Master’s Degree with Distinction.
In exceptional circumstances, the University may consider a portfolio of evidence from applicants who have appropriate professional experience which is equivalent to the learning outcomes of an Honours degree in lieu of academic qualifications.
If the University receives a large number of applicants for the project, the following desirable criteria may be applied to shortlist applicants for interview.
