摘要: 针对氦冷固态包层第一壁换热能力不足,通过在第一壁冷却管道内插入扭带进行强化换热。基于工程流体力学理论和 CFD 软件进行了第一壁的热流体分析。研究了在相同工况下不同扭带参数对换热效果的影响。结果表明,扭带可以有效提高第一壁的换热能力,在结构参数为带厚 3mm、带宽 11mm、扭率 2.5 时换热效果最佳,第一壁内壁面平均换热系数提升了 7.9%,结构温度升高量降低了8.6%。

Abstract: To address the issue of insufficient heat transfer capacity in the first wall (FW) of the helium-cooled ceramic breeder blanket, a twisted band was inserted into the cooling pipe to investigate enhanced heat transfer. Thermal fluid analysis on the first wall was conducted using principles from engineering fluid mechanics theory and CFD software. The impact of different parameters related to twisted band on heat transfer under identical operating conditions was examined. The simulation indicates that twisting band effectively enhances heat transfer capability in the first wall. Optimal heat transfer performance is achieved with a band thickness of 3mm, bandwidth of 11mm and twisting rate of 2.5. This configuration leads to an average increase in inner wall heat transfer coefficient by 7.9% while reducing structural temperature rise by 8.6%.

Key words:  First wall, Heat transfer enhancement, Thermal hydraulic analysis, Twisted band
