School of Engineering Sciences at KTH

Job description

The postdoctoral researcher will conduct experimental (and if suitable and possible numerical) studies of various types of flow instabilities both within boundary layers that develop on rotating cones of various sharpness and within an eccentric Taylor-Couette-Poiseuille (eTCP) flow for studies of flow instabilities and transition to turbulence. Both set-ups are already existent. The former has produced a number of publications (the latest being: Ref1, Ref2, Ref3), while the second is ready for use and has produced preliminary flow visualizations. For the project, measurements will be undertaken with a multi-component LDV system and stereoscopic PIV, hence experience in experimental fluid mechanics is instrumental. Linear stability analysis and numerical simulations are also planned in case of suitable candidates. This project will allow direct comparisons between experiments, simulations and with theory for a better understanding of centrifugally driven instabilities in flows in rotating configurations, particularly in the transitional and turbulent regimes.
The project is a collaboration between Ramis Örlü (OsloMet and KTH), Philipp Schlatter (FAU Erlangen and KTH), and Rebecca Lingwood (KTH).

  • A doctoral degree or an equivalent foreign degree. This eligibility requirement must be met no later than the time the employment decision is made.
  • Excellent oral and written communication skills in English as this will be required in day-to-day work.
  • Relevant submitted/published work in the field of fluid mechanics.

Preferred qualifications

  • A doctoral degree or an equivalent foreign degree, obtained within the last three years prior to the application deadline
  • A suitable background for this position would be a in Mechanical/Aerospace Engineering with a specialization in experimental fluid mechanics in the field of transition and turbulence. Knowledge of computational methods will be beneficial.
  • Applicants must possess the ability to work independently and perform critical analysis as well as possess good levels of cooperative and communicative abilities. This point is of importance since the main PIs are located in Oslo, Erlangen and Cambridge, while being affiliated with KTH, however, (emeritus professor) P. Henrik Alfredsson will also be involved in the project and is located in Stockholm.
  • Awareness of diversity and equal opportunity issues, with specific focus on gender equality
