About the position

We have a vacancy for a position as PhD candidate within the field of “Sustainable thermal stabilization of fish by-products and wastes assisted by heat pumping system”, at the Dep. of Energy and Process Engineering (EPT).

Fish and aquaculture industry in Norway generate high volume of by-products and wastes which are rich in proteins and valuable fats (omega-3). Most of the salmon slaughterhouses and fish processing plants are spread along the coast line and do not form solid clusters. The transportation of by-products to processing factories takes up to 24 hours, which decreases the quality and yield of the final product significantly and do not allow to utilize most part of the compounds for human consumption. These by-products are normally used for animal feed production, fish silage and generation of biogas.

The aim of the PhD work is the development of efficient and environmentally friendly thermal stabilization (both chilling and high temperature treatment) methods of different types and categories of fish by-products and wastes. 

The heating and chilling units (heat pumping systems) will utilize natural working fluids like ammonia, water or butane, individually or in combination and determine their potential for cost effective production of final product. The PhD work will address key challenges in physical properties of fish by-products and system design (heat exchangers and system optimization) as well as scale up.

PhD activity could be the determination of the performance of a new heat exchanger types, dryers and sterilizers for by-products stabilization. The candidate should be able to design and instrument a test rig in the lab and perform relevant experiments. The experimental data would be used to verify process simulations in order to determine the potential of systems and solutions for industrial applications. The PhD candidate will work closely with an experienced team at NTNU and relevant industrial partners in order to reach these aims.

The position's supervision is by Professor Trygve M. Eikevik. Professor Terese Løvås is the Head of the Department.

Main duties and responsibilities

  • Independently set up research plans and conduct them accordingly
  • Take lead in writing research papers under supervision
  • Contribute in supervising master students within the field
  • Comply with the PhD training programme of the Faculty of Engineering

Qualification requirements

The PhD student has proven strong theoretical skills within thermodynamics, food processing, and an interest to further develop these skills. The candidate is motivated for performing experimental research. The candidate is interested and skilled within theoretical as well as experimental studies. The candidate has a master's degree within mechanical engineering or equivalent. Good written and oral English language skills are required.

The PhD-position's main objective is to qualify for work in research positions. The qualification requirement is completion of a master’s degree or second degree (equivalent to 120 credits) with a strong academic background in mechanical engineering or equivalent education with a grade of B or better in terms of NTNU’s grading scale. Applicants with no letter grades from previous studies must have an equally good academic foundation. Applicants who are unable to meet these criteria may be considered only if they can document that they are particularly suitable candidates for education leading to a PhD degree.

The appointment is to be made in accordance with the regulations in force concerning State Employees and Civil Servants and national guidelines for appointment as PhD, postdoctor and research assistant.

NTNU is committed to following evaluation criteria for research quality according to The San Francisco Declaration on Research Assessment - DORA.
