KTH Royal Institute of Technology in Stockholm has grown to become one of Europe’s leading technical and engineering universities, as well as a key centre of intellectual talent and innovation. We are Sweden’s largest technical research and learning institution and home to students, researchers and faculty from around the world. Our research and education covers a wide area including natural sciences and all branches of engineering, as well as architecture, industrial management, urban planning, history and philosophy.

The department of Engineering mechanics pursues basic and applied research in biomechanics, composite mechanics, fluid mechanics, contact mechanics, fracture mechanics and fatigue, material mechanics and paper mechanics. In the applied research, there are strong connections to industry and public actors. This position is one of eight postdoc positions in the thematic areas developed at the department, namely,

- Biomechanics, Health and Biotechnology,

- Advanced Material and Structures, Energy,

- Transport and Future Mobility,

- Advanced Computing and Machine Learning.

Job description

As part of a cross-department initiative, the department of Engineering Mechanics announces a postdoc position within the thematic area Advanced Computing and Machine Learning on the topic of “Modelling fibre suspension flows using isogeometric analysis”.

The purpose of the project is to attain unprecedented accuracy and efficiency in modelling fibre suspension flows for forming applications and connect the results to structural simulations of the formed networks and composites. We will do it by engaging isogeometric analysis in modelling fibres and fibre interactions.

Fibre suspensions are the initial phase for many products such as paper or moulded composites. Controlling the density fluctuations and the orientation distribution is vital for achieving the target properties of the material. For example, in papermaking, the process starts from a dilute suspension and ends with a dry sheet that is essentially a network of bonded fibres. The paper sheet structure is defined by the flow and dewatering conditions in the forming section and is also affected by the chemistry. These factors must therefore be accounted for in the modelling framework.

The aim is to extend existing tools for multiscale numerical simulations of the sheet forming process, sheet consolidation (pressing), mechanical behaviour of the fibre network and eventual disintegration prior to recycling. The work of the post-doc will be partitioned into specific sub-projects: 1) implementing the isogeometric framework in the existing numerical code for fibre suspensions; 2) implementing isogeometric contact between the fibres to model friction and contact forces; 3) validation for single fibres and verification for suspension flow.

The work will be conducted in close collaboration between the groups in Fluid Mechanics and Solid Mechanics at KTH as well as with established groups in Linkoping University and Calgary University specializing in modelling fibre suspension flows and isogeometrical analysis.

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
  • Works in Stockholm, in close proximity to nature
