摘要
用Dubois&Samain与Lichtenberg等人提出的解释托卡马克中锯齿振荡的湍流模型 ,通过求解耦合了锯齿触发条件的一维输运方程 ,模拟了欧姆加热情形T 10托卡马克中锯齿振荡行为 ,同时对得到的数值结果作了分析 .与采用磁重联模型模拟得到的结果比较表明 ,采用湍流模型得到的数值结果与实验符合较好 。
By using the turbulence model proposed by Dubois & Samain and Lichtenberg, a transport code is presented to simulate a particular sawtooth discharge in T-10 tokamak under Ohmic heating situation. A trigger condition is also coupled into the transport code. The numerical results show that in many respects those with turbulent model agree with the experiment results. In contrast, it was impossible to obtain satisfactory simulations with the reconnection model.
