| 摘 要： | 目前管内电缆导体(CICC)压降的实验结果都是高空隙率(~35%)下测得的,而CFETR纵向场(Toroidal Field,TF)导体的设计偏向于较小的空隙率(~29%),压降实验数据方面的短缺,使得需要重新考虑目前Katheder关系式能否用于CFETR TF的压降估算。在CFETR TF导体的压降分析中,分别采用了修正的Katheder关系式和多孔介质模型对导体的压降进行比较,获得了更为保守的压降预测。

| Abstract: | At present, the experimental results of the cable - in - conduit conductor ( CICC ) pressure drop were measured at high void fraction (~35%), while the design of the CFETR toroidal field (TF) conductors tended to a low void fraction (~29%). The shortage of experimental data on pressure drop made it necessary to reconsider whether the Katheder correlation could be used for the pressure drop analysis of CFETR TF. In order to obtain a conservative pressure drop prediction, the modified Katheder and porous media correlation were employed. |
