摘要
基于托卡马克实验的L-H模转换过程中等离子体的输运特征,建立了一种简化的非线性等离子体输运模型。通过数值求解输运方程,得到了等离子体稳态温度分布剖面,成功模拟了托卡马克边缘输运势垒(ETB)的形成以及高辅助加热功率下的内部输运势垒(ITB)现象,并对比了有无输运势垒两种情况下托卡马克的能量约束效率。
A simplified nonlinear model of the plasma transport based on the plasma transport characteristics of the L-H mode transition in tokamak experiments has been made. The steady-state temperature profiles which illustrate the formation of the external transport barrier （ETB） and the internal transport barrier （ITB） phenomena with the high auxiliary heating power have been obtained by the numerical solutions of the transport equation. A comparison of the ETB energy confinement efficiency with the non-ETB case will be discussed.
