A PhD scholarship is available at the Department of Energy and Process Engineering (EPT) within the Refrigeration research group on the topic of "Natural Working Fluids and Mixtures - Heat Transfer and Pressure Drop in Pipes ".

The Refrigeration research group has long term expertise and a well-established network within of vapor compression systems, applying natural working fluids for various applications within different industrial sectors. In close cooperation with SINTEF, the group is involved in several national and international research projects in collaboration with the industry. This PhD position will be a part of the newly established research center “FME HighEFF” – Energy efficient and competitive industry for the future.

The background for the research work is the need to improve the design and calculation tools for evaporators and condenser in compact low charge refrigeration system to improve the energy efficiency. 

The international phase out of the HFC’s require new competence on natural working fluids heat transfer and pressure drop in low change systems. The knowledge of heat transfer in small pipes diameters, in compact heat exchangers, have to be measure and new correlations to be develop, both under evaporation and condensation conditions. The work will be experimental with develop of empirical correlation for selected natural working fluids including mixtures, at small diameters, less than 6 mm, and implement correlation in heat exchanger simulation program and the reliability of the calculations should be verified by experiments.


We seek a highly motivated candidate with a Master's degree (or equivalent) within refrigeration and/or in energy engineering. The candidate should present a strong interest for laboratory work. The candidate should document competence in modelling and simulation of complex multi-physical systems including heat- and mass transfer. A prior and concrete experience with the aforementioned disciplines are considered as an advantage.

Excellent English skills, spoken and written are required. Applicants from non-English speaking countries outside Europe must document English skills by an approved test. Approved tests are TOEFL, IELTS, and Cambridge Certificate in Advanced English (CAE) or Cambridge Certificate of Proficiency in English (CPE).
