Lulea University of Technology PhD Position in Fluid Mechanics

Hydropower is the largest source of renewable energy in the world and account for about 20% of the electricity production worldwide. It is facing new technical challenges with the introduction of renewable energy resources, refurbishment of aging machines, adapt to climate changes and meet new regulations.

To deal with these challenges the Swedish power industry together with the authorities and universities started the Swedish Hydropower Centre (SVC). SVC is a competence centre for education and research within the field of hydropower, whose vision is to secure a knowledge and competence supply for Sweden, for an efficient and reliable hydropower production. Luleå University of Technology is an active member of the centre.

Lulea University of Technology (LTU) offers an open position for a PhD candidate in the field of fluid mechanics in an exiting and growing environment using the latest techniques at the Division of Fluid Mechanics being part of the Department of Applied Physics and Mechanical Engineering. The department is a world leading institution within hydropower research in the fields of fluid mechanics, rotor-dynamics and tribology. It has access to world unique facilities such as generic models, full-scale hydropower machines and corresponding models, computer cluster and advanced measuring techniques.

Project description

The project is essentially experimental and related to pressure measurement technique.

The project aims firstly to investigate rotor-stator interaction in axial machines of Kaplan type. Detailed unsteady pressure measurements will be performed on a Kaplan model at Vattenfall Research and Development, Älvkarleby, Sweden. Fluid conditions at and outside the energy efficient operation point are of interest.

The second part of the project aims to develop flow measurements technique for low head machines. Pressure time or/and hybrid ultrasound/Winter-Kennedy method(s) may be used. Experiments will be supported by numerical investigations.

The project implies close collaboration with Chalmers, Andritz and Vattenfall in Sweden but also the Norwegian University of Science and Technology, Norway and University of Tehran, Iran.


Applicants should have an MSc/ degree within mechanical engineering or applied physics or equivalent. Previous experience in computational and/or experimental fluid mechanics is a merit.

Since male students are traditionally more numerous in this field of studies, female candidates are especially encouraged to apply. The position requires skills in written and spoken English but knowledge about French and/or Swedish is a merit, since our industrial and academic partners are from France, Switzerland, Canada, Sweden, and Norway.

The division of Fluid Mechanics

We provide an exiting and simulating environment of acknowledged experts, fellow PhD students and state of the art equipment within experimental and numerical fluid mechanics. Great effort is also spent on the working environment and gender issues. Strong international exchange and cooperation is encouraged.
