PhD position in fluid mechanics/hydropower

Norwegian University of Science and Technology (NTNU)

Trondheim, , NO

About the position

We have a vacancy for a PhD candidate at the Department of Energy and Process Engineering ( under the Faculty of Engineering ( . The department is equipped with state-of-the-art research infrastructure. Currently, more than 100 PhD students conduct research in the department. Follow the link ( to know more about the laboratories, researchers and activities.

The successful candidate is expected to conduct research in the Waterpower laboratory ( The laboratory has very rich history over 103 years in Norway and is equipped with one of the best research facilities of hydro turbines in the world. Its modern facilities include test rigs for Francis, Pelton and pump turbines. The laboratory offers a high-pressure pumping system, a long conduit to investigate flow measurement techniques, cavitation, speed of sound, water hammer, vibration, etc. Furthermore, the laboratory has access to the large supercomputers in Norway ( to carry out large simulations. Research group in the Waterpower laboratory comprises of five professors, one senior researcher, four postdoc fellows, five PhD students and 12-15 master students.

Currently, the laboratory is engaged in developing the next-generation of hydropower technology. For that energy flexibility is very important, and the hydro turbines must provide the necessary flexibility. The PhD candidate’s research will focus on fundamental/applied research on hydro turbine and address the relevant research questions. The research involves both experimental (laboratory) and numerical work. The laboratory work involves measurements using particle image velocimetry (PIV) and/or laser Doppler velocimetry (LDV) and/or pressure/strain depending on research need. Broad focus area will be one of these: (1) rotor stator interaction in Francis turbine, (2) vortex breakdown (3) fluid structure interaction, (4) vibrations and hydrodynamic damping, and (5) fatigue loading and lifetime of turbine blades.

The duration of PhD position is for maximum three years. The candidate will work in a team with the other researchers, postdocs, PhD candidates and master students. The Head of Department is Professor Terese Løvås. The main supervisor of the successful candidate will be Chirag Trivedi.

Duties of the position

  • To undertake the necessary courses as part of the PhD program.
  • To submit a research plan no later than 3 months from the date of joining.
  • Perform research and report progress on a regular basis in agreement with the supervisor(s).
  • Experimental and numerical research according to the research plan and the project objectives.
  • Laboratory work including building of test rig for experiments.
  • Complete the necessary course/training to work in the laboratory.
  • Communication and dissemination of research results under the supervision.

  • Interest in theoretical as well as experimental studies
  • Interest in communication and dissemination
  • Good written and communication English language skills
  • Good analytical and critical thinking skills

Preferred selection criteria

  • Knowledge of PIV/LDV/strain measurement techniques
  • Knowledge of programming/software, MATLAB, Python, ANSYS, LabView, etc.
  • Research quality and publications – Journal and conference papers
  • Genuine interest in research and willingness to learn

Personal characteristics

We are looking for dedicated, well-organized, team player with good communication skill and motivated to contribute to an inclusive work environment in the department.

We offer

The successful candidate will have access to the large research groups and possibility of exploring new research ideas as well as testing of ideas in the laboratory environment. The candidate will also have access to the state-of-the-art research laboratories in NTNU. The candidate will have possibility to present the research work in well-reputed international conference and to develop own research network.

Salary and conditions

PhD candidates are remunerated in code 1017, and are normally remunerated at gross from NOK 479 600 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 3 years.

Appointment to a PhD position requires that you are admitted to the PhD programme in Faculty of Engineering (  within three months of employment, and that you participate in an organized PhD programme during the employment period.

The engagement is to be made in accordance with the regulations in force concerning State Employees and Civil Servants, 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 daily.
