✦ Synopsis

In this Paper, heat slug propagation in the QUench Experiment on Long Length (QUELL) is studied with the 2-¯uid MI-THRANDIR model, which allows a ®nite coupling time between bundle and hole helium in a two-channel cable-in-conduit conductor. The same eight inductively heated and four resistively heated runs are considered in Part I. Good to very good agreement is shown between computed and experimental evolution of the conduit temperature T jk at downstream sensors, as opposed to the poor accuracy of the 1-¯uid simulations shown in Part I. The inlet mass ¯ow is typically slightly overestimated, as with the 1-¯uid model, resulting in a phase shift between computed and experimental T jk . Some parametric eects are also analyzed.

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
