About the position

We have a vacancy for a postdoctoral research fellow in the Thermo-fluids Group at the Department of Energy and Process Engineering, Faculty of Engineering, Norwegian University of Science and Technology.

The position is associated with the project "Tailoring flame dynamics in carbon-free combustors’’ in collaboration with the King Abdullah University of Science and Technology.

To reduce the carbon footprint associated with power generation, replacing traditional fuels by carbon-free alternatives such as blends of hydrogen carriers is highly desirable. But this is challenging as fuel properties significantly differ and thus strongly affect stability, efficiency and pollutant emissions. An aspect of utmost importance in gas turbine combustors is dynamic flame stability. The susceptibility of flames to upstream perturbations and their coupling with resonant combustor modes has been one of the biggest challenges in the development of modern high-efficiency, low-emission gas turbine combustors during the last decades. Considering hydrogen–ammonia mixtures as gas turbine fuel provides the unique opportunity for tailoring the fuel composition such that dynamic flame stability is vastly improved.

Until now, this aspect has not been investigated, but it promises a step change in the development of dynamically stable carbon-free gas turbines. The main objective of the project is to provide methods for the stable design of future combustor technology operating on carbon-free fuels. Specifically, (i) the effect of the spatial mixture profiles of hydrogen and ammonia on the dynamic response of canonical and gas-turbine-relevant flames will be revealed; and (ii) superior combustor stability will be demonstrated utilizing adaptive control of hydrogen and ammonia mixture profiles based on physical insight and machine learning. The postdoctoral researcher will be tasked with experimentally assessing the effect of the hydrogen–ammonia mixture profiles on the flame response to acoustic perturbations.

The position has a duration of 2 years. The starting daas soon as possible. 

The position's supervision and day-to day management is by Associate Professor Jonas Moeck.

Duties of the position

  • Development of an acoustic technique for measurements of heat release rate fluctuations in multi-fuel flames.
  • Assessment of the effect of the fuel mixture profile on the flame response to perturbations.
  • Assisting project partners in implementation and application of the developed techniques in a turbulent swirl flame experiment at elevated pressure.
  • Dissemination of the project results in scholarly journals and at international conferences.

Required selection criteria

A postdoctoral research fellowships is a qualification position in which the main objective is qualification for work in academic positions. You must have completed a Norwegian doctoral degree in engineering or physics, or corresponding foreign doctoral degree recognized as equivalent to a Norwegian doctoral degree.

If, for any reason, you have taken a career break or have had an atypical career and wish to disclose this in your application, the selection committee will take this into account, recognizing that the quantity of your research may be reduced as a result.

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.

Other required selection criteria: 

  • Strong expertise in fluids dynamics, acoustics, and combustion.
  • Experience in experimental work in a thermo-fluids context, preferably with combustion.
  • Excellent command of the English language; skilled in academic writing.
  • Proficient user of Matlab, Python or similar for data processing.

Preferred selection criteria

  • In-depth knowledge of combustion dynamics/thermoacoustic oscillations.
  • High-quality journal publications.
  • good written and oral English language skills
