Abstract :
Thermal-hydraulic modeling of cable-in conduit conductors (CICC) with a two-channel bundle/hole (B/H) topology contains several uncertainties in the BM coupling model. Here we study numerically with the 2-fluid MITHRANDIR code some effects of the major coupling parameters, i.e., degree of perforation of the B/H interface and heat transfer coefficient through it, on quench propagation in a two-channel CICC. A semi-quantitative discussion of the results is presented.
