Abstract :
The numerical method for shielding current density in axisymmetric high-Tc superconductors (HTS) applying the element-free Galerkin (EFG) method is presented. In the present study, the axisymmetric simulation code for analysing the time evolution of the shielding current density on HTS by using EFG is developed, and the shielding performances against the AC/DC-hybrid applied magnetic flux are evaluated by the code. The results of computations show that the shielding ability decreases as the applied magnetic flux of DC mode increases.
