介绍DIVIMP程序的基本思想和采用的物理模型,研究EAST托卡马克欧姆放电条件下碳杂质的产生与输运.模拟结果与实验测量具有较好的一致性,说明将该程序应用于EAST装置中杂质输运模拟的合理性.并利用DIVIMP程序预测EAST在8MW加热功率条件下钨杂质的输运特性.
Basic idea and physical models in DIVIMP are introduced and DIVIMP modelling of C impurity production and transport properties in edge plasma of EAST machine with ohmic heating are provided. Simulation results show favorable consistency with experimental measurements,demonstrating that the models coupled in DIVIMP are suitable for interpretive and predictive modelling of impurity transport in EAST machine. Transport properties of W impurity in EAST with heating power as high as 8MW are also predicted by DIVIMP modelling.
