The Paul Scherrer Institute PSI is the largest research institute for natural and engineering sciences within Switzerland. We perform cutting-edge research in the fields of future technologies, energy and climate, health innovation and fundamentals of nature. By performing fundamental and applied research, we work on sustainable solutions for major challenges facing society, science and economy. PSI is committed to the training of future generations. Therefore, about one quarter of our staff are post-docs, post-graduates or apprentices. Altogether, PSI employs 2200 people.

For the Laboratory for Waste Management - Transport Mechanics group and within the scope of a research project funded by SwissNuclear we are looking for a

Postdoctoral Fellow for machine learning enhanced multiscale reactive fluid dynamics

Your tasks

  • Conduct research in the area of cross-scale modelling of reactive multiphase flow (boiling) in complex heterogeneous materials, including conjugate heat transfer and surface reactivity (dissolution / precipitation) with application to nuclear reactor flows and CRUD formation
  • Use machine learning techniques to accelerate the numerical solvers and numerical analysis, the existing framework of the in-house scientific multiscale codes and machine learning tools will be the basis for further developments
  • 2D/3D multiphase numerical simulations using the CPU and GPU capabilities of the in-house lattice-Boltzmann codes, as well as commerical software
  • Co-development of codes, including benchmarking and validation
  • Publication of results in journals and conferences

Your profile

We are looking for a team player able to work independently with:
  • PhD degree in Mechanical or Nuclear Engineering / Natural Sciences / Environmental Sciences
  • Experience in numerical simulations, fluid dynamics and multiphase flows (ideally with lattice Boltzmann method)
  • Strong experience in numerical modelling and fluid dynamics, as well as programming experience (C / Cuda / Python)
  • Very good command of English is required (spoken and written)

We offer

Our institution is based on an interdisciplinary, innovative and dynamic collaboration. You will profit from a systematic training on the job, in addition to personal development possibilities and our pronounced vocational training culture. If you wish to optimally combine work and family life or other personal interests, we are able to support you with our modern employment conditions and the on-site infrastructure. 

Your employment contract is intially limited to 2 years with possible extension depending on the performance and future project availability.

For further information, please contact Dr Nikolaos Prasianakis, phone +41 56 310 24 15.

Please submit your application online by 21 June 2024 (including list of publications and addresses of referees) for the position as a Postdoctoral Fellow (index no. 4403-01).
