Job Type: FullTime
Deadline: 07 May 2021

This is NTNU

At NTNU, creating knowledge for a better world is the vision that unites our 7 400 employees and 42 000 students.

We are looking for dedicated employees to join us.

You will find more information about working at NTNU and the application process here .

About the position

We have a vacancy for a three-year PhD at the Department of Chemical Engineering, Faculty of Natural Science, NTNU. The position is funded through the NTNU Enabling Technologies Program (Enabling technologies - NTNU ).

The position is placed at the Department of Chemical Engineering, NTNU, in Trondheim under the supervision of Prof. Jannike Solsvik. The project has a close collaboration with Univ. Prof. Alfredo Soldati at the Institute of Fluid Mechanics and Heat Transfer, TU Wien. It is expected that the candidate is mobile and conduct long stay(s) at TU Wien.

The object of the project is to develop simulation methods of turbulent flows with dispersed large drops. The method is based on direct numerical simulations (DNS) for turbulence and on phase field method to describe the behavior of the interfaces. Please see, e.g., Soligo, G., Roccon, A., Soldati, A. (2019), Breakage, coalescence, and size distribution of surfactant-laden droplets in turbulent flow, J. Fluid Mech. 881, 244-282.

The position will start in August 2021.

Duties of the position

Develop in-house codes for multiphase turbulent flow in a channel. Codes are based on existing codes at NTNU and at TU Wien. The flow is in the dispersed regime with deformable fluid particles (i.e., drops or bubbles). The method is direct numerical simulations combined with the phase field method to include the fluid particle interfaces.

Required selection criteria

The PhD-position's main objective is to qualify for work in research positions. The qualification requirement is that you have completed a master’s degree or second degree (equivalent to 120 credits) with a strong academic background in [subject area] or equivalent education with a grade of B or better in terms of NTNU’s grading scale . If you do not have letter grades from previous studies, you must have an equally good academic foundation. If you are unable to meet these criteria you may be considered only if you can document that you are particularly suitable 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, post doctor and research assistant.

Required selection criteria

  • Strong knowledge of fluid mechanics with good appreciations of dispersed multi-phase flows
  • Documented experience with programming skills (preferably Fortran)
  • Great command of both written and spoken English

Additional selection criteria

  • Experience in direct numerical simulations
  • Experience in turbulence theory

Personal characteristics
  • Highly dedicated and committed
  • Ability to solve complex tasks independently
  • Good communication skills
