Post doctor in Gas Turbine Combustion Instabilities (IV-128/17)

Description 
A post-doctoral position in gas turbine combustion instabilities is available at the Department of Energy and Process Engineering (EPT) in the Fluid Mechanics research group. The position is funded by the Norwegian CCS Research Centre (NCCS) and one of the research tasks is dedicated to the effect of fuel flexibility on the stability and operational range of low-emission gas turbines in collaboration with Sintef Energy and 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. One of the most serious challenges facing the gas turbine industry is that low-NOx combustion technologies are prone to thermoacoustic instabilities, which limit the operating range and cause mechanical failure. It is expected that the problem of thermoacoustic instabilities will be exacerbated when operating fuel/reactant flexible schemes for CCS, such as hydrogen mixtures.


As an experienced researcher, you will take a leading role in a research project that will include a PhD student and will focus on combustion instabilities in annular combustors. The current project will utilise a unique atmospheric annular combustor fitted with an acoustic forcing system comprised of an azimuthal array of speakers capable of generating travelling, standing and mixed acoustic modes. Flame describing functions (FDF) will be measured using different methods to identify any effect of different mode types and flame-flame interactions for methane and methane/hydrogen blends. In addition, detailed investigations into the inlet velocity response for different acoustic modes will be undertaken using PIV and hot wire anemometry in two new facilities: i) a transverse forced jet apparatus and ii) an azimuthally forced jet. The role of swirl and transverse velocity fluctuations on the inlet response will be carefully investigated in order to identify the correct velocity scale for FDFs.


NTNU has excellent experimental facilities, including a new combustion laboratory for fundamental and applied research in gas turbine combustion with an emphasis on annular combustors supported by state-of-the-art, high-speed and low speed PIV systems, and laser induced fluorescence systems.


Qualifications

The successful candidate must have completed or be very near completion of a PhD in a subject in combustion or fluid mechanics and should have experience in advanced measurement methods and laser diagnostics. The candidate should also have good programming and data analysis skills. Candidates are expected to have a good publication record based on their career to date. A strong proficiency in one or more computing languages such as Matlab, Fortran, or C etc. is essential.


Excellent English skills, spoken and written, are required. Applicants from non-English-speaking countries outside Europe must document English skills by an approved test. Approved tests are TOEFL, IELTS, Cambridge Certificate in Advanced English (CAE) or Cambridge Certificate of Proficiency in English (CPE) 

Conditions
Postdoctoral candidates are remunerated in code 1352, and are normally remunerated at gross from NOK 485,700 per annum before tax. There will be a 2% deduction to the Norwegian Public Service Pension Fund from gross wage.

The appointment of the Postdoctoral fellows will be made according to Norwegian guidelines for universities and university colleges and to the general regulations regarding university employees.

The Postdoctoral fellowship is awarded for 2 years. Extension is possible pending available funding.

Anticipated commencement: As soon as possible.

For informal enquiries about the position please contact Professor James Dawson, james.r.dawson@ntnu.no or Associate Professor Nicholas Worth, nicholas.a.worth@ntnu.no

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

The engagement is to be made in accordance with the regulations in force concerning State Employees and Civil Servants. The positions adhere to the Norwegian Government's policy of balanced ethnicity, age and gender. Persons with immigrant background are encouraged to apply. NTNU´s objective is to increase the number of females in scientific positions. Female applicants are therefore encouraged to apply.
