Full Time


A position is open for a PhD student in the Fluid Mechanics group. The topic of the work is the interaction between waves and shear currents, and will be primarily experimental in nature. The ideal candidate is an experimental physicist, but see detailed description of skills below. The main supervisor will be Associate Professor Simen Å. Ellingsen.

Topical background: When a sheared flow is present beneath the water surface, the properties of surface waves can be dramatically changed. In coastal waters such shear currents abound, and can have profound effect on the wave forces acting on ships and structures, as well as the behaviour of the upper ocean. The latter is of direct importance to climate modelling, where good understanding the exchange of temperature between ocean and atmosphere is crucial. However, our understanding of wave-shear current interactions is very limited, and few experimental set-ups are able to address it. The group of dr Ellingsen have made extensive progress on the related theory in recent years, and experiments aim to test theoretical predictions as well as observe phenomena beyond theoretical state-of-the art.

Description of work: Experimental work will primarily be carried out in a newly developed laboratory for wave-shear current interactions in the Fluid Mechanics building in Trondheim, the only one of its kind in the world. Optical techniques (surface profilometry, particle image velocimetry). A significant portion of the work will be further development and implementation of measurement techniques and detailed design and control of fluid flow. The work focusses on basic understanding of underlying physical properties and will be published in the top journals in fluid mechanics.

Skills required: Experience with laboratory work is required, as well as demonstrated ability to develop technical solutions. The candidate should have good knowledge of basic electronics. Proficiency in programming is prerequisite, for lab control, data acquisition and data analysis. The candidate should have a strong physical background. A training in fluid mechanical theory is an advantage, although a strong background in physics and mathematics will allow the candidate to quickly learn the necessary theory. The ideal background is experimental physics, although excellent candidates from mechanical and marine engineering will also be well equipped. Note: Experience in computational fluid mechanics using software such as Fluent, StarCCM or Open Foam, while useful in general, is not particularly relevant to this position and does not qualify.

General qualifications: The position requires a Master’s degree in physics, mechanical or marine engineering, or applied mathematics. The successful candidate should be enthusiastic and highly motivated and be willing to work both independently and with other researchers. The successful candidate must also fulfill the requirement for admission to a doctoral program.


PhD Candidates are remunerated in code 1017, and are normally remunerated at gross NOK 436 900 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 of 3 years duration. Depending on the candidate’s background and ability, the position can be extended to 4 years. If the position is for 4 years, one year is dedicated to duty work at the Department.
