摘要

液态铅铋合金（Lead-Bismuth Eutectic

LBE）是加速器驱动次临界系统（Accelerator driven subcritical

ADS）重要的散裂靶材料和冷却剂候选材料

其热力学物理性质是ADS研发过程中必须解决的基础问题。通过对已有定律的推算

得出液态铅铋合金熔沸点、密度、比热容、粘度、热导率的热物性公式;并拟合了其他学者的实验研究数据

得出计算铅铋物性的拟合公式。通过对比分析可知:拟合公式与已有定律推算公式趋向一致

吻合较好;且拟合公式更趋近实验值

精确度高

最大偏差不超过1%。

Abstract

Background:Liquid lead-bismuth eutectic(LBE) is important spallation target materials and candidate coolant materials in accelerator driven subcritical(ADS)system.Purpose:Its thermodynamic physical properties are keys to understand the basic problems in ADS R&D.Methods:By the calculation of scientific laws as well as fitting other scholars’ experimental results

we tried to obtain the above thermodynamics physical properties.Results:By the calculation

we got formula about characteristic temperatures

density

specific heat

viscosity and thermal conductivity of liquid lead-bismuth alloy.And by fitting other scholars’ experimental results

we got the fitting formula.Conclusions:Finally

by the contrast analysis

we found that the fitting formula and calculation formula agree well

and fitting formula more approaches the experimental value with a high accuracy whose differential deviation is not over 1%.
