Outline of Final Research Achievements

The energy systems which combined liquid hydrogen and superconducting devices are considered widely, but there are few research examples. When a high temperature superconducting coil cooled by liquid hydrogen, the coil temperature changing are depended on thermal disturbance, the Joule heat, the cooling heat by liquid hydrogen, and the thermal conductivity. In past research, the temperature distribution of a real coil wound up into a pancake form that considered not only the heat conduction of the superconducting wire longitudinal direction in past researches but also the radial direction. In this study, I analyzed the heat transmission and temperature behavior on a high temperature superconducting coil using non-steady-state the two-dimensional heat conduction equation analysis by calculus of finite difference method
