对稳定的液态金属钠沸腾两相流动压降特性进行了实验研究和理论分析．得到了不同工况下液钠沸腾两相流动压降特性的实验数据，建立了环形通道内液钠两相流动压降特性计算模型Ｎａ－ＴＰＤＰ，并将Ｌｏｃｋｈａｒｔ－Ｍａｒｔｉｎｅｌｉ，Ｋａｉｓｅｒ－Ｐｅｐｐｌｅｒ，Ｃｈｅｎ－Ｋａｌｉｓｈ等人不同的两相摩擦压降倍增因子关系式进行了计算分析和比较．计算结果表明：Ｋａｉｓｅｒ－Ｐｅｐｐｌｅｒ的两相摩擦压降倍增因子计算式与文中的实验结果符合较好．
The experimental study and theoretical analysis of the steady-state two-phase flow pressure drop in liquid metal sodium boiling were carried out. The experimental data of the pressure drop characteristics of liquid-to-liquid two-phase flow in different conditions were obtained. The Na-TPDP model was established for the pressure drop of liquid-liquid two-phase flow in the annular channel. Lockhart-Martineli, Kaiser-Peppler, Chen- Kalish, who different two-phase frictional pressure drop multiplication factor relationship between the calculation analysis and comparison. The calculation results show that the Kaiser-Peppler double-phase frictional pressure drop multiplication factor is in good agreement with the experimental results in the paper.
