Finite Element Analysis of Quench Propagation Velocity in Bi-2223/Ag Superconducting Multifilamentary Tape

Article Preview

Abstract:

Quench propagation velocity is an important parameter to the stability and protection issues of superconducting magnet. In this paper, the finite element method (FEM) numerical simulation of quench propagation velocity has been performed for using the powerful analysis software COSMOS by establishing a suitable thermal analysis model of Bi-2223/Ag superconducting multifilamentary tape. The effects of quench energy and operating temperature on the quench propagation velocity have been studied. The analysis shows that the simulation result basically coincides with the experimental result.
