摘要
分析了HT-7U超导Tokamak核聚变装置中环向场超导线圈上的涡流损耗热产生的机理和迫流式超临界氦对流换热等过程。特别针对等离子体快速破裂时,极短时间内在环向场磁体中所产生的较大的涡流损耗而引起的焦耳热,对环向场线圈盒与超导磁体之间的热传递过程加以研究。本文采用国际上通用的有限元分析软件ANSYS5.7进行计算,计算所得的结果较为乐观。
In this paper, eddy current for the Toroidal field superconducting magnet in HT7U Tokamak device and the heat removal through the forced flow supercritical helium has been investigated. The thermal analysis is made for the particular status of a plasma disruption. During the disruption, a significant amount of energy is deposited in the case, so particular attention is paid to the heat transfer between the case and the winding. Some results determined by using the code of ANSYS5.7 is satisfactory.
