Trainee for the investigation of two-phase flow in cryogenic pulsating heat pipes

vor 2 Wochen

Villigen, Aargau, Schweiz Paul Scherrer Institute Vollzeit CHF 60'000 - CHF 80'000 pro Jahr
Trainee for the investigation of two-phase flow in cryogenic pulsating heat pipes Your tasks For superconducting magnet applications in particle accelerators, a highly efficient cooling device working in cryogenic conditions is crucial. Pulsating Heat Pipes (PHPs) are promising candidates which, combined with a cryocooler, will cool superconducting magnets at cryogenic temperature (in this case ~30 K). The principle is to transfer heat from an evaporator to a condenser using phase change and oscillations of vapor bubbles and liquid slugs circulating in a serpentine tube. The better understanding and prediction of the PHP behavior through numerical modelling of heat transport and two-phase flow combined with targeted experimental campaigns for benchmarking the models is the aim of this internship project
The tasks include:
  • Conduct a literature survey on the state of research on cryogenic PHPs
  • Extend an existing 2D ANSYS FLUENT model of neon PHP
  • Participate in an experimental campaign of cryogenic PHP characterization and in the result analysis
  • Benchmark the 2D model with the experimental results
  • Write an internship report
Your profile
  • You are a student in engineering or physics, and you are at least in your first year of the Master degree but you have not yet completed your master's thesis
  • Ideally, you have already gained knowledge in fluid dynamics as well as heat and mass transfer
  • Knowledge of cryogenics, programming experience using ANSYS FLUENT or similar software and expertise working in Linux environment is a plus
  • As a team‐oriented and communicative person you enjoy working in an interdisciplinary group
  • Good knowledge of English is mandatory
We offer Our institution is based on an interdisciplinary, innovative and dynamic collaboration
The contract will be limited to 3 months
