✦ Synopsis

The experimental setup for heat slug propagation at zero current and ®eld in the QUench Experiment on Long Length (QUELL) is described and re-evaluated. Eight inductively heated and four resistively heated runs are considered and analyzed with the 1-¯uid GANDALF model, which assumes perfect coupling between bundle and hole helium in the two-channel cable-in-conduit conductor (CICC). Although adequate to predict the hydraulic response, the 1-¯uid model exhibits an intrinsic limitation to accurately simulate the evolution of the conduit temperature at dierent sensor locations during heat slug propagation. In general it appears that the analysis of this type of slow transients requires a 2-¯uid model, as considered in Part II of the present study.
