Efficient boiling and condensation are fundamental to thermal management in refrigeration, air conditioning, electronics cooling and energy systems. The transition toward slow Global Warming Potential refrigerants is essential for reducing environmental impact, but these fluids introduce new challenges associated with altered wetting behaviour, nucleation, liquid and vapour transport, dryout and flooding. This PhD project will experimentally investigate droplet shedding, film breakup, flooding, heat transfer coefficient and pressure drop in ribbed and finned micro structured surfaces during flow condensation of low surface tension refrigerants. The successful candidate will work at at the Thermal Two-Phase Flow Laboratory (http://folk.ntnu.no/fernandi/) at NTNU’s main Gløshaugen campus in Trondheim, Norway. Experiments will be conducted with state-of-the-art equipment and experimental techniques. The candidate will be part of a friendly working environment, with close interaction with our postdoc, PhD and MSc candidates working in our group. The position will be supervised by Professor Maria Fernandino. Are you motivated to take a step towards a doctorate and open up exciting career opportunities? As a PhD Candidate with us, you will work to achieve your doctorate, and at the same time gain valuable experience that qualifies you for a further career in higher education and research, in and outside academia. Your immediate leader will be the Head of Department.

About the project SurPhase is a Horizon Europe Marie Skłodowska-Curie Actions (MSCA) Doctoral Network training 12 doctoral candidates in surface engineering and phase-change heat transfer for low-global-warming-potential refrigerants. SurPhase brings together four academic beneficiaries: the University of Birmingham, Sabanci University, Norwegian University of Science and Technology and University of Padova, supported by Ericsson, Arçelik, Fraunhofer IFAM, ANSYS and Hexxcell. The programme combines academic and industrial research, international mobility, network-wide training and cross-sector secondments.

Duties of the position

• Design, planning and running of condensation experiments • Contribute to academic publications, project reports and other dissemination activities • Participate in meetings with supervisors and colleagues • Engage in secondments as part of the project training activities • Participate in structured training programs and network eventsorganized by the consortium • Collaborate with other doctoral candidates in the consortium Be prepared for changes to your work duties after employment.

Required selection criteria To apply for this MSCA Training position, applicants must fulfil the following criteria:

• At the time of recruitment by the host organisation, candidates must not have resided or carried out their main activity, such as work or studies, in the country of the recruiting beneficiary for more than12 months during the 36 months immediately preceding their recruitment date. • Applicants must be willing and able to undertake the planned international academic and industrial secondments within the SurPhase network. General required selection criteria:

• You must meet the requirements for admission to the Faculty's Doctoral Programme, see Section 6-1 of the PhD regulations for more information. • You must have a relevant Master's degree in mechanical engineering, thermal engineering, applied physics or equivalent. Your degree must include a major independent project (minimum 30 ECTS) equivalent to a Master’s thesis. • Master students can apply, but the Master's degree must be obtained and documented before starting the position and no later than June 2027. • You must have a strong and relevant academic background from your previous studies and have an average grade from your Master's degree study, or equivalent education, which is equal to B or better compared to NTNU's grading scale. If you do not have letter grades from previous studies, you must have an equally good academic foundation. If you have a weaker academic background, you may be considered if you can document that you are exceptionally suited for a PhD education, for example through relevant work experience and/or peer-reviewed academic works. • You must have good oral and written presentation skills in English. Specific requirements for the proposed project:

• You must have an academically relevant background within fluid mechanics and heat transfer, demonstrated through projects, activities, and/or theses. • You must have good experience in experimental work. • You must have programming experience with Matlab, Python or similar. The appointment is to be made in accordance with NTNUs guidelines for recruitment positions for general criteria for the position.

Preferred selection criteria

• •Experience conducting fluids and heat transfer experiments (e.g. scientific imaging techniques, IR cameras).
• •Experience with image processing
• •Strong fundamentals in condensation and two-phase flow heat transfer will be considered an advantage
• •Previous experience writing and contributing to peer-reviewed journal articles will be considered an advantage

Personal characteristics

• Enthusiastic and highly motivated • Show curiosity and a strong motivation for the subject • Able to work independently and in a team • Work constructively under pressure or in the face of adversity • Flexible and open to adjusting the plan for the project as needed Emphasis will be placed on personal qualities.

We offer

• State-of-the-art laboratories and equipment • A strong group of researchers focused on fluid mechanics and heat transfer • A strong and international professional environment • Open and inclusive working environment with committed colleagues • Favorable terms as a member of the Norwegian Public Service Pension Fund (SPK) • Free, optional Norwegian language training at a basic level (A2) As a PhD Candidate at NTNU, you will have access to employee benefits.

Diversity Diversity is a strength, and at NTNU we aim to be an employer that reflects the diversity in society and that makes use of the potential of the population's collective skills. Our vision is Knowledge for a better world and our values ​​are creative, critical, constructive and respectful. We believe that an organization that is equal, diverse and gender-balanced is essential for us to achieve our goals. The Department of Energy and Process Engineering (EPT) has established EPT Women in Science. The group is focused on supporting female Research Assistants, PhD Candidates, Postdoctoral Fellows and permanent academic employees within the Department. This support aims to help develop the academic careers of female employees, and is also made visible to our student body, to encourage them to consider an academic path.
