PhD in combustion instabilities IV-161/17

Description
A PhD position is available at the Department of Energy and Process Engineering, within the Fluid Mechanics group.

Gas turbines are essential for a clean and reliable energy supply. They play a crucial role in the presence of increasing installation of intermittent renewable sources that require back-up power. Gas turbine power generation capacity is thus projected to increase significantly over the coming decades, but improved operational and fuel flexibility is required to fully exploit the potential for reducing carbon footprint. One of the biggest challenges in developing modern low-emission combustor technology for gas turbine applications is the occurrence of combustion instabilities. This dynamic phenomenon arises from an interaction of fluctuations in the heat release rate and the acoustic resonances of the combustor and manifests in high-amplitude pressure and flame oscillations that limit the operating range and are detrimental for the engine.

The PhD project will focus on theoretical and numerical modeling of thermoacoustic instability phenomena relevant for gas turbine engines. Specifically, acoustic-hydrodynamic-flame interaction in systems with multiple heat sources and high modal density, such as annular or can-annular combustors, will be addressed. Linear and nonlinear models for non-compact acoustic-flame interaction and the effect of transverse waves will be developed and implemented, allowing for improved prediction and analysis of thermoacoustic oscillations in laboratory and industrial configurations.

EPT provides an excellent environment for in-depth studies of thermoacoustic phenomena, with an increasing number of people working on combustion instabilities and state-of-the-art experimental facilities available. The present PhD project will concentrate on theoretical and numerical work but a strong collaboration with experimentalists in the group is envisaged.

Qualification
We are looking for highly motivated candidates with a Masters degree (or equivalent) in Physics, Engineering or Applied Mathematics, with strong expertise in at least two of the following fields: fluid dynamics, acoustics, combustion, numerical methods. Advanced knowledge of Matlab and/or Python as well as an excellent command of the English language are required.

The candidate will be required to work in Trondheim at the Department of Energy and Process Engineering, NTNU.

Conditions
PhD Candidates are remunerated in code 1017, and are normally remunerated at gross NOK 432,300 before tax. There will be a 2 % deduction to the Norwegian Public Service Pension Fund from gross wage.

Engagement as a PhD Candidate is done in accordance with “Regulation concerning terms and conditions of employment for the posts of post-doctoral research fellow, research fellow, research assistant and resident”, given by the Ministry of Education and Research of 19.07.2010. The goal of the positions is to obtain a PhD degree. Applicants will engage in an organized PhD training program, and appointment requires approval of the applicants plan for a PhD study within three months from the date of commencement.

The position is for 3 years. Depending on the candidate’s background and ability, the position can be extended to 4 years with 25% teaching duties at the Department.

For informal enquiries about the position please contact Prof. Jonas Moeck (jonas.moeck@tu-berlin.de) or Prof. James Dawson (james.r.dawson@ntnu.no).
