摘　　要：对国际热核聚变实验反应堆纵向场(ITERIF)导体室温氮气流动阻力进行了理论计算,在计算的基础上设计了1套ITER导体流动阻力实验平台,然后利用这个实验平台对1根78m长的ITERTF导体进行了室温下氮气流动阻力实验,得到实验值和计算值的最大偏差为10%;同时对实验得到的雷诺数和摩擦系数的关系进行了重新拟合,得到了新的摩擦系数经验关系式;最后对ITERTF导体低温下的流动阻力进行了理论计算,得到TF导体超临界氦流动阻力约为441Pa/m。Theoretical calculation of International Thermonuclear Experimental Reactor Toroidal Field （IFER TF） pressure-drop with room-temperature nitrogen and a related test platform were presented.One 78 m TF conductor was tested by this device,and the maximum deviation between test result and theoretically calculated value was 10%.The correlation of Reynolds number and friction factor was also refitted at the same time.The pressure-drop of ITER TF at low temperature was calculated and the unit pressure-drop value of 441 Pa/m was obtained.
