| 摘 要： | 现有的法拉第屏蔽(FS)冷却结构无法满足未来EAST长脉冲稳态运行的要求,需要进行优化改进.通过理论和数值模拟方法,对FS原有冷却结构进行了优化设计,并获得了改进后FS冷却管道的流速和压力分布.通过比较不同进口条件下FS流体压降和结构温度分布情况,获得了适合优化后FS结构运行的流动参数,为未来ICRH天线FS的运行提供了理论指导.

| Abstract: | In order to meet the requirement of long pulse and steady-state operation of EAST in future, the existing cooling structure of Faraday shield (FS) needs to be optimized. Through theoretical and numerical simulation method, the optimized design of original FS cooled structure is achieved, as well as the distributions of velocity and pressure of improved FS cooled tube are obtained. By comparing the fluid pressure drop and structural temperature distributions of FS under different inlet conditions, the adaptive operational flow parameters for optimized FS structure are obtained, which provide theoretical guidance for future operation of ICRH antenna FS. |
