| 摘 要： | 利用SOLPS和DINA程序，对偏滤器的数值模拟进行综合研究。结合HL-2M装置，针对偏滤器的结构优化、脱靶物理过程、偏滤器送气与抽气、垂直位移事件(VDE)等问题进行了模拟研究。分析了偏滤器靶板位形以及脱靶对偏滤器靶板热载荷的影响，研究了偏滤器的送气位置、送气速率、抽气速率等因素对于偏滤器性能的影响；同时，利用DINA程序对HL-2M装置的VDE过程进行了预测分析，并给出了HL-2M装置发生VDE过程的等离子体电流剖面变化，从而为HL-2M装置的偏滤器结构设计和分析提供输入数据。

| Abstract: | The integrated simulation of the divertor is implemented. Many issues including the optimization of the divertor configuration, physical process of detachment, gas puffing and pumping, and vertical displacement event (VDE) on HL-2M are investigated by applying the SOLPS and DINA codes. The effects of divertor plates geometry and detachment on the deposited heat load of divertor plates are evaluated. And the impacts of the gas puffing position, the gas puffing rate and the pumping rate on the divertor performance are also discussed. In addition, the VDEs on HL-2M are also predicted by the DINA code, and the variation of plasma current profile during the VDEs is given, thus the input for the design and analysis of the HL-2M divertor is provided. |
