Description

In the framework of the R&D for the LHC cooling scheme (i.e. heat exchanger pipe), Superfluid helium (He II) flows were studied at Grenoble. Initially convection of pure liquid and later counter and co-current two-phase flow were investigated. In this talk, we will mainly focus on co-current HeII two-phase flow, as it is the solution adopted for the LHC. Original sensors such as capacitive probes or thermal 'flag' will be presented. Video sequences of He II two-phase flow will also be shown.
