【Abstract】 It is difficult to measure the detailed flow fields of Chinese liquid metal LiPb experimental loop Dragon-Ⅱ(High temperature heat convection,about 700 ℃).Three dimensions numerical analysis of the LiPb flow and heat transfer in loop has been carried out by using the CFD code FLUENT.The detailed flow fields,which include temperature,velocity,pressure and heat transfer of liquid LiPb in the test sample area,are presented to use as a reference for the corrosion experiment analysis of CLAM(China low activation martensitic) steel in flowing LiPb.更多还原
