About the positio

A PhD position is available at the Department of Energy and Process Engineering, in the Fluids Mechanics group.

The appointment has a duration of 3 years as a researcher towards the degree of PhD. The appointment is financed by the Norwegian Research Council as part of the Low Emission Research Centre. The position reports to Associate Professor Nicholas Worth.

If stationary gas turbines are to continue to play a key role in meeting future environmental challenges and provide sustainable power in the face of growing demand, the potential of fuel flexible operation needs to be fully realised. To limit climate impact, future gas turbine technology must be capable of operating using alternative low or zero carbon fuels and fuel blends in order to support the emergence of zero net CO2 emission energy systems. However, there are a number of significant technical challenges which must be overcome when operating with new fuels or fuel-blends. New and existing engines must be designed to prevent combustion instabilities, flashback, and maintain low NOx emissions during operation.

The current project will focus on the fuel flexible operation of a scaled SGT750 combustor using H2/NH3 fuel blends, with the aim of better understanding the flashback, emissions performance, and thermoacoustic stability of the system, with a focus on the latter topic. The project will involve conducting a series of laboratory experiments using state-of-the-art measurement methods such as high-speed imaging, and acoustic measurements using dynamic pressure sensors to measure the flame response. These measurements will help improve our understanding of the flame structure, dynamic response, and emissions performance for a practical configuration, and help identify beneficial fuel splits and operating states, aiding the rapid development of zero carbon gas turbine technology.

You will report to Head of Department Terese Løvås

Duties of the position

  • Design, setup, and optimisation of experiments, including accurate characterisation of boundary conditions.
  • Measurement of heat release rate response using high speed chemiluminescence of relevant species, dynamic pressure measurements, and emissions measurements.
  • Assessments of stability, and emissions performance across a wide range of operating conditions.
  • Dissemination of results in scholarly journals and at international conferences.

Required selection criteria

The PhD-position's main objective is to qualify for work in research positions. The qualification requirement is that you have completed a master’s degree or second degree (equivalent to 120 credits) with a strong academic background in fluid mechanics  or equivalent education with a grade of B or better in terms of NTNU’s grading scale. If you do not have letter grades from previous studies, you must have an equally good academic foundation. If you are unable to meet these criteria you may be considered only if you can document that you are particularly suitable for education leading to a PhD degree.

The appointment is to be made in accordance with the regulations in force concerning State Employees and Civil Servants and national guidelines for appointment as PhD, post doctor and research assistant.

  • A Masters (or second) degree in engineering, applied mathematics, physics or equivalent
  • Strong background in fundamental or applied fluid mechanics.
  • Programming skills in MATLAB, C, Python, or similar packages.
  • Excellent command of the English language, and skilled in academic writing

Preferred selection criteria

  • Experience with state-of-the-art experimental fluid mechanics measurements (e.g., high-speed imaging, hot-wire, particle image velocimetry, laser-Doppler anemometry, dynamic pressure measurements).

Personal characteristics

  • Enthusiastic and highly motivated
  • Able to work effectively by themselves and in a team
  • Able to work in a structured and goal orientated manner
  • Able to work in a multi-cultural environment.
