A thermal-hydraulic measurement on simulated counterflow cooled HTS cable
geometry has been conducted. A description has been provided of the significant terms of
the energy balances needed to analyze and design an operating HTS cable system.
Measurements on a simulated HTS cable are discussed that were conducted at three
different heating conditions and flow rates. The measured temperature profiles showed
differences between the return stream and the solid tube which depended on the flow rate
and heating conditions.
The measurements demonstrate the qualitative effects of the various energy balance
terms needed to analyze a cryogenic HTS cable system. These conditions were sufficient to
provide responses that demonstrated the interaction between the inter-stream and axial
conduction.
