Abstract :
Supercritical Helium (SHe) is frequently used for the large-scale magnet cooling in many applications. In the present study, the flow and heat transfer characteristics of SHe in the mini-tubes of about 1.0-2.0 mm in diameters are numerically investigated to provide the useful information for the design of the cooling configuration of Cable-in-Conduits Conductors (CICCs) and the related. And a simplified equivalent model is also proposed to estimate the flow and heat transfer characteristics of SHe in the complicated configuration of CICCs.
