About the project

To limit climate impact and ensure energy security, future gas turbine technology (amongst other technologies) must be fuel flexible and capable of operating on zero carbon fuels and fuel blends. However, the turbulent mixing, transport properties and combustion physics of fuels such as hydrogen and ammonia are significantly different to conventional fossil fuels and are not well understood.

We are looking to recruit up to 4 PhD positions that will focus on understanding the fundamental physics of turbulent mixing and combustion of hydrogen and ammonia (and their blends) which is the subject of several research projects including an ERC Synergy Grant – HYROPE and an EU project InsigH2t. Hydrogen is highly diffusive, extremely reactive, and we do not understand how the turbulent burning rate scales with pressure which is important for practical applications. Ammonia is a hydrogen carrier (a way to store and transport hydrogen) but has a poor reactivity and can result in significant NOx emissions. The overriding aim of the research is to understand, in detail, the impact of turbulent mixing, new turbulent mixing strategies using active grids, and the effect of pressure on the behaviour of these zero carbon fuels. However, this is a multi-dimensional problem with many constituent parts that need to be investigated in detail. Experiments will be conducted in a range of experimental facilities from atmospheric to high pressure. A range of advanced laser diagnostic measurements methods including high and low speed PIV, PLIF of various species, emissions, and chemiluminescence systems will be used to understand the impact of turbulent scalar mixing, the effect of pressure and structure of turbulent flames for hydrogen, flame stability and methods to control emissions of ammonia and various blends.

The positions are funded from the ERC synergy grant, HYROPE which will involve collaborations with other researchers at ETH Zurich, IMFT/CNRS in Toulouse and TU Darmstadt. The EU Project, InsigH2t and internal funding linked to these projects.

About the position

Are you motivated to undertake a doctorate and embark on new exciting career opportunities that contribute to the major societal challenge of clean and secure energy? As a PhD Candidate with us, you will work to achieve your doctorate, and at the same time gain valuable experience that qualifies you for a further career in higher education and research, in and outside academia.

As a member of the Thermofluids research group at EPT, we are looking for talented, ambitious researchers who are motivated to solve difficult problems and conduct fundamental research at the highest international level. You will attend internationally leading conferences, present and publish your work in high impact journals.

Your immediate leader will be Professor James Dawson. You will also work with Professor Jason Hearst, Dr. Håkon Nygård, and Dr. Eirik Æsøy.

Duties of the position

You will design, develop, setup, and optimise of experiments, including accurate characterisation of boundary conditions.
You will conduct detailed measurements of turbulence, turbulent mixing, flame structure, chemiluminescence, emissions measurements using a range of different experimental configurations and laser diagnostics.
You will develop and implement new analysis methods to experimental data.
You will contribute and collaborate with the group and international collaborators.
You will disseminate your results in scholarly journals and at international conferences.

Be prepared for changes to your work duties after employment.

Required selection criteria

You must have a relevant Master's degree in engineering, applied mathematics, physics or equivalent. Your course of study must correspond to a five-year Norwegian course, where 120 credits have been obtained at master's level. Master students can apply, but the master's degree must be obtained and documented before starting the position and no later than September 2026, unless applying through the integrated PhD programme.
You must have a strong academic background from your previous studies and have an average grade from your Master's degree study, or equivalent education, which is equal to B or better compared to NTNU's grading scale. If you do not have letter grades from previous studies, you must have an equally good academic foundation. If you have a weaker grade background, you may be considered if you can document that you are particularly suitable for a PhD education.
You must meet the requirements for admission to the faculty's Doctoral Programme.
