強制冷却超電導体の安定性におよぼす熱擾乱の時間および空間分布の影響

抄録

Influence of the thermal disturbances of various temporal and spatial profiles on the stability limit of a cable-in-conduit superconducting coil, forced-flow cooled by supercritical helium, has been numerically analyzed. The maximum deviation of the stability limits for any temporal profiles from those for rectangular temporal profile is 45 percent. In the case where the length of thermal disturbance is ninety hydraulic diameter and less, the effect of the axial-heat conduction in superconductor on the stabiliry limit is not negligible. The transient valiation of the maximum conductor temperature is almost similar in both the quasi-rectangular and quasi-parabolic spatial profiles of the thermal disturbances.
