Summary

A NEW METHOD HAS BEEN DEVELOPED FOR NUMERICAL ANALYSIS OF QUENCH TRANSIENTS IN CABLE-IN-CONDUIT FORCED-FLOW COOLED SUPERCONDUCTORS. IN THIS METHOD, THE QUENCH TRANSIENTS ARE SEPARATED INTO 2 TIME-DOMAINS, FOR WHICH DIFFERENT MODELS ARE INTRODUCED. THE FIRST MODEL INCLUDES THE THERMAL CONDUCTION OF THE CONDUCTOR, HEAT TRANSFER AND SUPERCRITICAL HELIUM FLOW. IN THE SECOND MODEL 2 ASSUMPTIONS ON THE THERMAL CONDUCTION AND THE HEAT TRANSFER ARE INTRODUCED SO AS TO OMIT THE CALCULATION OF THE THERMAL CONDUCTION EQUATION OF THE CONDUCTOR. THE SOLUTION OBTAINED USING THE PRESENT METHOD HAS ALMOST THE SAME ACCURACY AS THAT OBTAINED BY THE ORDINARY METHOD (FIRST MODEL).
