Session 3: Heat Transfer R&D
- Bernardo Bordini (CERN)
- Gerard Willering (CERN)
Description
The aim of the session is to present the state of the art in the study of heat transport from superconducting cables to liquid helium. Numerical models will be discussed, as well as the latest results of experimental work. We aim for a lively discussion on future experimental work to validate numerical models in the highly-relevant millisecond-loss regime (UFO losses in the LHC). Moreover, we want to devote one slot to the conception of an experimental program towards validated damage-levels for fast beam-loss events in superconducting accelerator magnets.

The results obtained with Finite Element models help to better understand the heat transfer mechanism in complex structures, like Nb-Ti Rutherford type cables. With FE models, it is possible to implement the real geometry with different levels of precision, giving the possibility to take into consideration the properties on interfaces between copper, helium and kapton, as well as phase changes...

Comprehending the cooling of superconducting magnets with superfluid helium requires the knowledge of heat and mass transfer in different size and time scales. Moreover, steady-state, transient and phase change must be considered in order to cover a wide spectrum of working conditions and thermal events to which these magnets are subjected. Focusing on the transient heat and mass transfer to...
