Background and research activities

With a master of science degree in space egineering I conducted doctoral studies within the field of fluid mechanics in 2002 and has been working within the discipline ever since. Today my activities cover both research, teaching and strategic assignments. I am the faculty programme director for the space engineering programme and also vice chairman of the board of employment at LTU. 

My research cover:

  • Lubrication - primarily grease lubrication and grease flow dynamics.This field includes rheology and flow of non-Newtoinian materials (shear thinning-, viscoelastic-, and multiphase materials), general continuum mechanics.
  • Large scale plasma (solar wind) flow. Sun/Earth interaction: magnetic reconnection, ion escape from the terrrestrial atmosphere. 
  • Wind power: improvement and design of open gears (heavily connects to the general lubrication/grase flow activity).
  • Multi-phase flows with application to SMC (Sheet Moulding Compound).

Teaching

  • Electromagnetic field theory F0007T. Examiner.
  • Engineering science (programming in Matlab) F0051T/R0007R. Examiner.
  • Continuum mechanics F7030T. Exercises.
  • Advanced continuum mechanics F7023T. Lectures on constitutive modelling, non-Newtonian fluids, rheology and objectivity.
  • Master's thesis project - specialization in Aerospace P7010R. Examiner.
  • Plasma physics F7010R. Lectures on magnetohydrodynamics (MHD), diffusion, and instability.
