About the position

A two-year postdoc position is available at Department of Energy and Process Engineering (EPT), Norwegian University of Science and Technology (NTNU), Trondheim, Norway. The position will start in October 2020.

The project will focus on the study of the heat transfer process occurring in the boundary layer of a liquid flow in the presence of bubbles and evaporation phenomena. The fact that small scales and gas-liquid interfaces (bubbles) are involved, will require the development of an adequate experimental approach for flow visualization and temperature field measurements, which will constitute an important part of the project. Understanding the heat transfer mechanisms and especially the main factors limiting a more efficient heat transfer under these conditions will open new possibilities for optimization and new solutions for emerging technologies. 

The selected candidate will join our ongoing activities at the Thermal Two-Phase Flow Laboratory (ThTPFLab) at the Department of Energy and Process Engineering, NTNU. The group counts with state-of-the-art laboratories for the characterization of thermal flows at the microscale.

The group has been working on different experimental techniques for temperature measurement, such as nanofabrication of temperature sensors in the order of few microns, measurement of the surface temperature field based on high-speed high-resolution infrared (IR) visualization and visualization of the temperature field using laser induce fluorescence. Micro-PIV and an inverted fluorescence microscope are available for characterization of the flow field. Present activities in the group include flow in microchannels for biological applications, thermal boundary layers in mini-channels, dropwise condensation and dynamics of droplets on superhydrophobic and super-repellent surfaces.

For more information on the ThTPFLab group, please follow this link.

The Head of Department is Professor Terese Løvås. The candidate will be supervised by Professor Maria Fernandino and Professor Carlos Dorao. 

Duties of the position

The successful candidate is expected to:

  • Do research work, in collaboration with other members of the group and the two supervisors
  • Assist and collaborate with other Postdoc and PhD candidates in the group
  • Be active in the dissemination of results

Required selection criteria

A postdoctoral research fellowships is a qualification position in which the main objective is qualification for work in academic positions. Completion of a Norwegian doctoral degree in Physics, Fluid Mechanics, Mechanical Engineering or closely related field, or corresponding foreign doctoral degree recognized as equivalent to a Norwegian doctoral degree is required.

If, for any reason, you have taken a career break or have had an atypical career and wish to disclose this in your application, the selection committee will take this into account, recognizing that the quantity of your research may be reduced as a result.

Essential qualifications and skills

  • Applicants must hold a degree equivalent to a Norwegian doctoral degree in Physics, Fluid Mechanics, Mechanical Engineering or a closely related field. Only applicants with an approved doctoral thesis and public defence by the application deadline are eligible for appointment.
  • Strong academic qualifications and record of international peer-reviewed publications.
  • Understanding of the physics of heat transfer during phase change is mandatory.
  • Strong documented competence within the field of experimental fluid mechanics involving gas-liquid flows and heat transfer.
  • Documented experience - in the form of published paper(s) - in performing fluid flow visualization using at least one of the following techniques: micro-PIV, infrared (IR) and/or high-speed visualization, or other relevant optical visualization techniques for the position.
  • Hands-on skills with designing and setting up experimental facilities in the lab.
  • Good language skills: a good command of both written and spoken English.

Preferred knowledge and skills

  • Knowledge of optics and optical systems
  • Experience with image analysis
  • Experience in the visualization of droplets and bubbles.
  • Programming experience in Labview and Matlab

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, post doctor and research assistant.

Personal characteristics

  • Innovative and curiosity-driven.
  • Scientific and technical proficiency, high ambitions and problem-solving.
  • Interpersonal communication skills and the ability to work as part of a team.
  • Willingness to work together with PhD and/or Master/Bachelor students in the specialty field.

In the evaluation of which candidate is best qualified, emphasis will be placed on education, experience and personal suitability.
