Abstract

A two-dimensional flux-flow model is constructed to investigate the electromagnetic characteristics of a melt cast process BSCCO-2212 tube. Solving the flux-flow equilibrium equation with numerical method, we obtain the distributions of the current density, the flux density, and the flux-flow resistivity. The effect of inner radii on the critical current is also investigated. Based on the characteristic of the average flux-flow resistivity, we simulate the quenching process of the tube by ANSYS. The calculation results are significant for optimization and safety design of the current lead
