本文提出了一个计算模型，描述了为国际热核聚变实验堆（ITER）设计的电缆管道超导体中正常区的形成和演化。由于ITER电缆的特殊几何形状，该模型将两个冷却通道中的氦动量和电缆组件的温度分开处理。该模型的数值实现进行了讨论，结合一个很好的解决方案的算法的选择。特别是，选择的解决方案的过程是基于一个隐式迎风有限元技术与自适应时间步长和网格大小调整的可能性。时间步长和网格自适应程序进行了说明。文中还介绍了该模型的应用实例。(C)北京：科学出版社. Inc.
A computational model describing the initiation and evolution of normal zones in the cable-in-conduit superconductors designed for the international thermonuclear experimental reactor (ITER) is presented. Because of the particular geometry of the ITER cables, the model treats separately the helium momenta in the two cooling channels and the temperatures of the cable constituents. The numerical implementation of the model is discussed in conjunction with the selection of a well-suited solution algorithm. In particular, the solution procedure chosen is based on an implicit upwind finite element technique with adaptive time step and mesh size adjustment possibilities. The time step and mesh adaption procedures are described. Examples of application of the model are also reported. (C) 1996 Academic Press. Inc.
