School of Engineering Sciences at KTH

Job description

Non-Newtonian fluids are all around us in nature and industry (from biological fluids to avalanches). Complex fluids flow often more irregularly than simple fluids such as water, and interact very differently with surfaces. MUCUS project funded by European Research Council (ERC) improves understanding and prediction of complex fluids’ flow over surfaces. As part of the ERC project, we announce an experimental postdoc position in wetting and surface-interaction of non-Newtonian fluids, particularly viscoelastic, yield-stress or shear-thinning fluids. This will benefit industries dealing with complex fluids, and in long term contribute to enable improved predictions of natural disasters.

As a postdoctoral researcher you will utilize experimental techniques to generate new physical insight, which together with our pioneering simulations will lead to a great impact. Our main interests are related to droplet wetting, impact and sliding on surfaces with different topography and wettability, including the role of contact line hysteresis. Depending on the candidate’s interests, wall-bounded flows and multiphase can be studied as well.

These experiments will amplify our recent experimental efforts in the flow physics of  complex fluids and surfaces. There are different measurement techniques and setups in the Fluid Physics lab available for the candidate to work with, including surface modification techniques in micro- and macroscale, a rheometer with visual access, optical and non-optical velocity and visualization techniques (high-speed cameras, OCT, PIV, MRI).

The work will be conducted in close collaboration between the groups of Tammisola and other research groups in Fluid Physics Lab (Fredrik Lundell and Shervin Bagheri), and the candidate will also interact with other researchers within FLOW and with the international partners of the YIELDGAP Network for yield-stress fluids, for example experimental groups in France, Italy, UK and Switzerland.

What we offer

  • A position at a leading technical university that generates knowledge and skills for a sustainable future
  • Engaged and ambitious colleagues along with a creative, international and dynamic working environment in fluid dynamics and materials.
  • Work in Stockholm, in close proximity to nature
  • Help to relocate and be settled in Sweden and at KTH
