PhD position in Combustion Dynamics of Hydrogen Flames for Zero Emission Power Generation
About the position
A PhD position is available at the Department of Energy and Process Engineering within the Thermo-fluids research group at NTNU. The appointment has a duration of 3 years and is funded by the Norwegian CCS Research Centre (NCCS) led by Sintef Energy. One of the main work packages within NCCS is dedicated to accelerating the transition to zero emission gas turbines using hydrogen in collaboration with Ansaldo Energia.
State-of-the-art gas turbine power plants are efficient, complex machines optimised to burn natural gas usually at constant load. However, they have the potential to be both fuel flexible and operationally flexible which means they are ideally placed to play a major role in the energy transition to renewable technologies which produce power intermittently. Excess power from renewables cannot be easily stored but can be used to produce so-called green hydrogen which can be burned in gas turbines when needed and stabilise the grid. It is well known that one of the most serious challenges limiting the operation of gas turbines are thermoacoustic instabilities and their underlying combustion dynamics. A better scientific understanding and tools to predict them are needed as the effect of pure and diluted hydrogen is currently not well understood.
The position will be supervised by Professor James Dawson at NTNU and co-supervised Professor Thierry Schuller at IMFT (Institute of Fluid Mechanics Toulouse). Research activities will be based at both the Department of Energy and Process Engineering at NTNU to investigate various fundamental aspects of hydrogen and potentially ammonia flames and numerical simulations will be performed at IMFT.
The head of the department is Professor Terese Løvås.
Duties of the position
The motivation of the research is the reduction to zero CO2 emissions in large-scale power generation applications. One very promising approach is to operate gas turbines on zero-carbon fuels such as hydrogen or ammonia (a hydrogen carrier). The PhD research will focus on how these fuels affect the thermoacoustic response and combustion dynamics. Recent research in our groups has found that hydrogen flames are sensitive to a much wider range of perturbation frequencies which means they may be more susceptible to self-excited thermoacoustic instabilities than methane flames and that careful burner design may be employed to cancel out specific frequency ranges where gas turbines need to operate. The aim of the PhD project is to better understand this and other important phenomena by conducting detailed experimental investigations at NTNU and high-fidelity Large Eddy Simulations at IMFT. This knowledge is a crucial enabling step to zero-emission gas turbines and large-scale reductions in CO2 emissions as set out by the EU.
The research project requires unique experimental capabilities and numerical expertise. The successful candidate will have access to state of the art experimental facilities integrating different advanced experimental techniques including Particle Image Velocity (PIF) and Laser Induced Fluorescence (LIF) at NTNU as well as expertise and training in high-fidelity numerical simulations at IMFT. The successful candidate will be joining two internationally active research groups in fluid mechanics and laser diagnostics with experienced post-doctoral researchers as well as PhD students. Several joint publications in internationally leading scientific journals and attendance at international conferences is expected.
The expected start date is as soon as possible.
