Background: On the basis of liquid metal LiPb flow in the Single-coolant Lithium Lead-Test Blanket Module(SLL-TBM) system for ITER

the liquid metal flows slowly in a quasi-static way in the magnetic field. Purpose: The effects of liquid metal LiPb flow and heat transfer can provide references for the thermal analysis. Methods: The common software Fluent combined with compiled program was used in the computational simulation for various heat flux of the first wall. Results: The temperature of the whole flow passage increased with rise of the first wall heat flux density

especially that of L1 runner near the first wall. The temperature and velocity of the L1 runner changed prominently

producing larger change of the induction magnetic field and induction current density

and the corresponding Loren magnetic affected the flow and heat exchange. Conclusion: The induction magnetic field and induction current density have influence on the temperature distribution. These results can provide basis for the thermal-hydraulic design.
