Comparison between the predictions of the thermo-hydraulic code Gandalf and the results of a long length instrumented CICC module experiment Original Research Article

Thermo-hydraulic modeling of cable in conduit conductors (CICC) contains one main uncertainty in the heat exchange coefficient used in the different possible fluid regimes. Nowadays validation of codes, by comparison with data from experiments involving long length instrumented conductors, is one of the main technique for assessing the design tools for the large magnets foreseen in the next generation fusion machines. To this purpose, a broad disturbance scenario has to be investigated to confirm the magnetʹs stability versus normal and off-normal working conditions. In this paper a comparison between the predictions of the code Gandalf and the data obtained from an instrumented NbTi conductor module is carried out.
