Job Description

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
