摘要

稀土（Re）Ba2Cu3O7-x（ReBCO）无绝缘（NI）线圈因其优异的电磁和热性能而受到广泛关注。然而，无绝缘线圈中匝间分流的存在导致数值模拟的复杂性增加。本文提出了一种改进的 J 模型，并设计了相应的显隐混合算法来计算 NI 线圈。数值结果与实验数据和电路模型十分吻合。同时还提出了同质化模型来模拟背景磁体中的大规模 NI 线圈。改进后的 J 模型具有良好的精度和快速的计算速度，也可用于高效求解绝缘线圈的电磁场。

A modified J model for efficiently calculating the electromagnetic fields of ReBCO no-insulation pancake coils using an explicit–implicit hybrid algorithm

Rare-earth (Re)Ba₂Cu₃O_7−x (ReBCO) no-insulation (NI) coil is widely concerned due to its excellent electromagnetic and thermal properties. However, the presence of the turn-to-turn shunts in NI coils leads to that complexity of numerical simulation is increased. In this paper, a modified J model is proposed and the corresponding explicit–implicit hybrid algorithm is designed to calculate NI coils. The numerical results are in good agreement with the experimental data and the circuit model. The homogenization model is also proposed to simulate the large-scale NI coils in the background magnets. The modified J model has good accuracy and fast calculation speed, which can also be used to solve electromagnetic fields of insulation coils efficiently.
