NORWEGIAN UNIVERSITY OF SCIENCE & TECHNOLOGY - NTNU
About the job
The postdoctoral fellowship position is a temporary position where the main goal is to qualify for work in senior academic positions. The appointment has a duration of 2 years and 8 months and is financed by the Department of Energy and Process Engineering at NTNU. Your immediate leader will be Professor Nicholas Worth .
The current project involves the development and application of Tomographic measurements methods to various problems in fluid dynamics and combustion science. Computed Tomography in fluid mechanics commonly involves measuring multiple projections from a scalar field of interest, and then solving an underdetermined linear system of equations to reconstruct the most likely three-dimensional distribution of the scalar field. In the current project the method will be applied to both reacting and non-reacting flows. The project will also involve the development of image or view splitting methods, to gather multiple projections from different imaging angles onto a single imaging sensor.
The reacting flow application will involve the reconstruction of asymmetric ammonia blended flames in a simplified model gas-turbine combustor, and multiple interacting flames in an annular combustor. Various frequencies of light will be collected in order to understand the flame topology and reaction structure as well as the dynamics during nominally stable turbulent combustion, and thermoacoustically unstable operation. The results will be important for the development of low emission gas turbine engines operating with novel ammonia fuel blends.
In terms of non-reacting flows, the three-dimensional absorption of oxygen into a turbulent water channel flow will be investigated, using Laser Induced Fluorescence of oxygen. If time permits, three-dimensional particle tracking velocimetry and novel particle sizing investigations may also be conducted in this application. The results will be important to future climate modelling efforts, allowing the more precise description of oxygen transport into the oceans as a function of important turbulence parameters.
Duties of the position
- Design, setup, and optimisation of experiments, including accurate characterisation of boundary conditions.
- Design, setup and test novel view spitting approaches in order to utilise a large number of imaging views suitable for the reconstruction of scalar fields.
- High-speed measurement and Tomographic reconstruction of various chemiluminescence emissions measurements from asymmetric ammonia blended flames.
- Volumetric LIF measurement and Tomographic reconstruction of oxygen concentration in a large water channel under various turbulent inlet conditions.
- Dissemination of results in scholarly journals and at international conferences.
Required selection criteria
The successful applicant should be enthusiastic and highly motivated as well as being able to work effectively by themselves and in a team. Specific qualifications are listed below:

- Strong background in fundamental or applied fluid mechanics.
- Previous peer-reviewed publications in well regarded journals.
- Programming skills in MATLAB, C, Python, or similar packages.
- Experience with state-of-the-art experimental fluid mechanics measurements (e.g., high-speed imaging, PLIF, dynamic pressure measurements, hot-wire, particle image velocimetry, laser-Doppler anemometry).
- Excellent written and oral English language skills
The appointment is to be made in accordance with Regulations on terms of employment for positions such as postdoctoral fellow, Ph.D Candidate, research assistant and specialist candidate (in Norwegian).
Preferred selection criteria
- Experience with Computer Aided Design (CAD).
- Experience in designing, setting up, and conducting measurements of reacting and non-reacting flows.
- Experience with Tomographic methods in fluid flows, including the use of and development of these methods.
- Familiarity with camera view splitting, spatial calibration methods, laser sheet illumination intensity calibration.
- Experience with particle tracking velocimetry, and particle sizing methods.
- Experience mentoring other PhD or Masters students.
Salary and conditions
As a Postdoctoral Fellow (code 1352) you are normally paid from gross NOK 584 700 per annum before tax, depending on qualifications and seniority. From the salary, 2% is deducted as a contribution to the Norwegian Public Service Pension Fund
The period of employment is 2 years and 8 months.
The engagement is to be made in accordance with the regulations in force concerning State Employees and Civil Servants (in Norwegian), and the acts relating to Control of the Export of Strategic Goods, Services and Technology. Candidates who by assessment of the application and attachment are seen to conflict with the criteria in the latter law will be prohibited from recruitment to NTNU.
After the appointment you must assume that there may be changes in the area of work.
It is a prerequisite you can be present at and accessible to the institution on a daily basis.
About the application
The application and supporting documentation to be used as the basis for the assessment must be in English.
Publications and other scientific work must follow the application. Please note that your application will be considered based solely on information submitted by the application deadline. You must therefore ensure that your application clearly demonstrates how your skills and experience fulfil the criteria specified above.
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 application must include:
- CV and certificates
- Transcripts and diplomas for bachelor’s-, master’s- and PhD degrees. If you have not yet completed your Ph.D, you must provide confirmation on your estimated date for the doctoral dissertation, or that your PhD thesis has been submitted
- Academic works – published or unpublished – that you would like to be considered in the assessment (up to 3 items)
- A research plan, see below
- Name and contact information of three referees
Candidates are required to submit a one-page sketch on how they plan to use their scientific background and research ambitions to address the research challenges of this position. You should describe ideas for future investigations; it is understood that the topic may not be your specialty – the key is to demonstrate understanding of excellent experimental research in the context of this position. For examples of recent experiments in our laboratory, refer to https://doi.org/10.1016/j.proci.2022.08.051
If all, or parts, of your education has been taken abroad, we also ask you to attach documentation of the scope and quality of your entire education. Description of the documentation required can be found here. If you already have a statement from NOKUT, please attach this as well.
