About the job

We have a vacancy for a PhD position at Department of Chemical Engineering. The position is part of the FRIPRO project “Establishing next-generation pioneering models for interface mass transfer, breakup and coalescence in turbulent flow”, funded by the Norwegian Research Council.

The understanding of droplet dynamics in turbulent flow is important for a variety of industrial processes. In this project we are interested in the detailed analyses of drop-turbulence interactions. We are particularly interested in understanding the drop-turbulence interactions in the cases where such interactions result in breakup of droplets. Numerical simulations of turbulent flow (resolved scales) with dispersed droplets (described by the phase field method) can provide the necessary flow fields needed to analyse the drop-turbulence interactions. Canonical flows such as the channel will be adopted for the multiphase flow simulations.

The qualified candidate must have deep interest in high-performance computations of physical phenomena of multiphase turbulent flows. This requests that the candidate must hold good knowledge of turbulence theory. The work will include programming (modification and further developments of existing codes). Basic codes written in Fortran will be provided to the candidate. The candidate must expect to communicate the work to both the research group at NTNU and international collaborating groups.

The position will include stay abroad with collaborating groups, mainly TU Madrid.

For a position as a PhD Candidate, the goal is a completed doctoral education up to an obtained doctoral degree.

You will report to your supervisor.

Duties of the position

  • Conduct high-quality research
  • Communicate the research work with others
  • Take the leading role in writing research papers
  • Comply with the Ph.D. training program of the faculty
  • Conduct short stays abroad with collaborating research groups
  • The candidate must expect to perform programming in Fortran to modify existing codes and develop new programs for data analyses.

Required selection criteria

  • You must have a professionally relevant background in fluid mechanics, computational physics, aerodynamics, chemical engineering, or similar.
  • Your education must correspond to a five-year Norwegian degree program, where 120 credits are obtained at master's level
  • You must have a strong academic background from your previous studies and an average grade from the master's degree program, or equivalent education, which is equal to B or better compared with NTNU's grading scale. If you do not have letter grades from previous studies, you must have an equally good academic basis. If you have a weaker grade background, you may be assessed if you can document that you are particularly suitable for a PhD education.
  • You must meet the requirements for admission to the faculty's doctoral program
  • You must have strong interest and experience with programming languages: Fortran or C, and Matlab or Python
  • You must have good knowledge of turbulence theory
  • You must have good written and oral English language skills.

The appointment is to be made in accordance with  Regulations concerning the degrees of Philosophiae Doctor (PhD) and Philosodophiae Doctor (PhD) in artistic research national guidelines for appointment as PhD, post doctor and research assistant  

Preferred selection criteria

  • Experience with direct numerical simulations (DNS) is advantageous
  • Experience with high-performance computing (HPC) is advantageous
  • Experience with numerical methods is advantageous
  • Experience with multiphase flows is advantageous, and particularly interfaced resolved methods such as the phase field or volume of fluid
  • Experience with coherent turbulent structures is advantageous

Personal characteristics

  • Demonstrated ability to work independently as well as collaboratively
  • Demonstrated ability to quickly acquire knowledge in new topics
  • Dedicated for scientific and academic work
  • Passion for uncovering new knowledge and communicating it to others

Emphasis will be placed on personal and interpersonal qualities.
