在ITER的等离子体参考场景中，由于脉冲工作电流，中央螺线管(CS)线圈被提交给脉冲热负载。这些磁体的所有导管中电缆导体(CICC)都是用超临界氦强制流动冷却的。热工水力计算的目的是估计转移到与低温制冷机相连的热水浴的热负荷(静态和脉冲)。这些计算是在ITER CS系统上进行的，因为它的设计实际上是冻结的。通过对两个数值程序1-Vincenta(Efemov Institute，Saint-Petersburg)和第一个低温回路的交叉校核，对两种模型进行了比较。2-Gandalf(CryoSoft)，它模拟一个CICC(1-D)和相关的低温电路(Flower)，必须进行调整才能相关。Gandalf模型处理煎饼101经历最严重的条件。Vincenta代码的结果由ITER组织获得。
During the plasma reference scenario of ITER, the Central Solenoid (CS) coils are submitted to pulsed heat loads due to pulse operating currents. All Cable‐In‐Conduit‐Conductors (CICC) of these magnets are cooled with a forced flow of supercritical helium. Thermohydraulic calculations aim to estimate the heat loads (static and pulsed) transferred to the thermal bath connected with the cryogenic refrigerator.These calculations are performed on the ITER CS system as its design is practically frozen. Comparison of the models is made through cross checking of two numerical codes: 1‐ Vincenta (Efremov Institute, Saint‐Petersburg) a quasi‐3D code which can model all the CS coil CICCs in parallel and the first cryogenic loop. 2‐ Gandalf (CryoSoft) which models one CICC (1‐D) and an associated cryogenic circuit (Flower) which has to be adapted in order to be relevant.The Gandalf model deals with the pancake 101 experiencing the most severe conditions. The results of Vincenta code are procured by ITER Organization...
