摘　　要：研究聚变堆单冷液态锂铅实验包层模块(SLL)中液态金属磁流体动力学(MHD)效应,在磁场环境下对处于缓慢准静态流动的不同流速的液态金属LiPb流动和传热的影响进行数值模拟和分析,为包层热工分析提供依据。研究表明:液态金属处于准静态缓慢流动时,流速的增加,流道换热会改善;流速增加到一定程度后,流道温度整体都下降;流速的增加对感应磁场及感应电流的整体分布影响不是特别明显。Abstract： The magnetohydrodynamics （MHD） effects of liquid metal LiPb flow in the single-coolant lithium lead-test blanket module （SLL-TBM） system for ITER are studied. The liquid metal flows slowly in a quasi-static way in the magnetic field. The flow and heat transfer effects of different inlet velocity of the liquid metal are simulated and analyzed. The results can provide references for the thermal analysis and design of the blanket. The results show that as the velocity increases, the heat transfer effectiveness increases and the temperature decreases. There is a little influence on the distribution of the induction magnetic field and induction current when changing the velocity.
