Abstract :
The aim of this paper is to take into account the thin layer of insulation of a superconducting tape or a superconducting coil to calculate heat transfer during a quench. The main problem is that this thin layer is very difficult to mesh in finite-element method. In this paper, we propose a modified factor of the convection coefficient obtained due to an analytical solution of the heat equation. The aim of this modification is to take into account the thickness of the resin, which bands a thin coil, or a superconducting tape immersed in cryogenic bath. Introducing this modified factor leads to a significant simplification of the 3-D thermal study because the diffusion in the resin is taken into account due to the modifying factor.
