内冷式磁体线圈降温过程的数值模拟

A Numberical Simulation of the Cool─down Process of the Magnet Coils with Inner Cooling Type

双饼空心内冷式磁体线圈降温过程的数值模拟比较复杂．文章分析了常规迭代方法的特点和存在的不足，经过采用改进的交替迭代法进行处理，效果明显。加快了计算收敛速度，计算时间是常规方法的１／１０．

It is rather complicated to numerically simulate the cool- down process of the magnet coils with inner cooling type. We have anaylized the characteristics and disadvantages of the conventional iteration in this .paper. Through improved alternating iteration, we have gotten a clear efficiency, such as convegence acceleration. The caculating time has been shorted to be 10% of the conventional iteration.
