M&M: Multi-conductor Mithrandir code for the simulation of thermal-hydraulic transients in superconducting magnets

The analysis of superconducting magnets can require the simultaneous simula tion of several conductors. The multi-conductor Mithrandir (M&M) code has b een developed for this purpose from the Mithrandir code (Zanino R, De Pale S, Bottura L. J Fus Energy 1995;14:25), which was used for the simulation o f thermal-hydraulic transients of single two-channel cable-in-conduit condu ctors (CICCs) cooled by supercritical helium. The M&M code is able to descr ibe simultaneously an arbitrary number of one-or two-channel conductors, al lowing for different kinds of coupling between them, and for different topo logies of the assembly. The new code has been validated in three different situations, leading to good agreement both with results obtained with Mithr andir and with experimental data. (C) 2000 Elsevier Science Ltd.
