About the job

For a position as a PhD Candidate, the goal is a completed doctoral education up to an obtained doctoral degree.

The Department of Electric Energy (IEL) at NTNU has a vacancy for a full-time 100% position as a PhD Candidate within the field of electric insulation systems and numerical and experimental characterization of the flow dynamics in power transformer windings.

A secure energy supply requires a robust and resilient power and transmission system. Significant investment in electric power systems is needed in the coming decade to meet growing energy demands. Reinvestments should be done in a way that minimizes environmental impact and preserves reliability. Liquid-filled high-voltage power transformers play a crucial role in electric production, transmission, and distribution systems. The liquid serves as electrical insulation and cooling for the transformer windings.

Mineral oils, derived from non-renewable crude oil with low biodegradability, have long been the dominant insulating liquids. However, new alternatives with environmental, HSE, and technical benefits have emerged. The NewLifT project, which this PhD position is associated with, focuses on the thermal properties of these new insulating liquids. The PhD will work with a multidisciplinary research team to examine the impact of liquid viscosity on cooling capabilities, particularly at low temperatures. The research may involve both experimental and numerical/analytic work, and the candidate's background and interests will determine the balance. The PhD will focus on modelling and measuring liquid flow in a laboratory flow rig.

The work of this project will be associated with the project NewLifT (New Liquids for Transformers), which is a collaborative project involving NTNU, SINTEF and several national and international industry partners. The prospective candidate will be part of a project team that works in close collaboration with NTNU, SINTEF and other project partners.

The main supervisor will be Professor Kaveh Niayesh (NTNU) and the co-supervisor will be Dr. Camilla Espedal (SINTEF Energy Research).

Your immediate leader is the Head of Department.

Duties of the position

The candidate will collaborate with other team players to perform a systematic investigation (either experimental or numerical) on thermal behavior of different insulating liquids.
The candidate will be expected to participate in and perform modelling and experimental studies of various insulation liquids. The balance between modelling and experiments can be adjusted according to the candidate's background and preferences.
- The modelling involves making models for describing the impact of different liquid properties, in particular viscosity, on their cooling capability especially at very low temperatures (subzero). This could for instance include computational fluid dynamics or simpler lumped models.
- The experimental part involves studying and measuring flow and temperature distributions in an already-built experimental rig at room and subzero temperatures.
The candidate will disseminate scientific findings via conference presentations and journal publications.
The candidate will complete academic training consisting of course work corresponding to minimum 30 ECTS.

Required selection criteria

You must have a professional relevant background in Electric Power Engineering. Applicants with a professional relevant background in Physics or Mathematics are also eligible to apply.
Your education must correspond to a five-year Norwegian degree program, where 120 credits are obtained at master's level.
You must have a strong academic background from your previous studies and an average grade from the master's degree program, or equivalent education, which is equal to B or better compared with NTNU's grading scale. If you do not have letter grades from previous studies, you must have an equally good academic basis. If you have a weaker grade background, you may be assessed if you can document that you are particularly suitable for a PhD education.
Master's students can apply, but the master's degree must be obtained and documented by autumn 2023.
You must meet the requirements for admission to the faculty's doctoral program.
Good written and oral English language skills. Applicants from non-English speaking countries outside EU/EEA/Switzerland must provide preliminary documentation of English language proficiency, in terms of an approved test. The following tests can be used: TOEFL, IELTS and Cambridge Certificate in Advanced English (CAE) or Cambridge Certificate of Proficiency in English (CPE). Minimum scores are:
- TOEFL: 600 (paper-based test), 92 (Internet-based test)
- IELTS: 6.5, with no section lower than 5.5 (only Academic IELTS test accepted)
Further assessment of both written and oral English language skills, and the ability to communicate fluently, will be conducted in the continued selection process and during any interviews for the shortlisted applicants.

The appointment is to be made in accordance with Regulations on terms of employment for positions such as postdoctoral fellow, Phd candidate, research assistant and specialist candidate and Regulations concerning the degrees of Philosophiae Doctor (PhD) and Philosodophiae Doctor (PhD) in artistic research national guidelines for appointment as PhD, post doctor and research assistant

Preferred selection criteria

Basic knowledge of fluid mechanics and heat transport theory.
Experience with or knowledge of computational physics and numerical methods, such as finite-element methods and/or computational fluid dynamics.
Experience with running and building lab set-ups could be beneficial.

Personal characteristics

Inquisitive, self-motivated and self-driven with a strong ability to work both independently, and in cooperation with others when required.
Good communications skills, both orally and in writing.
Structured, targeted and solution-oriented.
Scientific mindset

Emphasis will be placed on personal and interpersonal qualities.

We offer

exciting and stimulating tasks in a strong international academic environment
an open and inclusive work environment with dedicated colleagues
favourable terms in the Norwegian Public Service Pension Fund
employee benefits

Salary and conditions

As a PhD candidate (code 1017) you are normally paid from gross NOK 532 200 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 employment contract is for three years, with the possibility of a fourth year.

The option of 4-year employment would imply 1 year of duties as teaching assistant for the department and may be offered to a candidate with clear motivation and ability for such work, if the department sees the need. This will be clarified during and after any interview.

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