摘要
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 characteristics of two phase pressure drop for liquid sodium are experimentally studied and theoretically analyzed. Under different experimental conditions, lots of data of liquid sodium boiling and its two phase pressure drop are acquired. On the basis of conservation equations, a computation code, Na TPDP, which can predict the two phase pressure drop in an annular channel, is developed. The calculated results are in agreement with experimental data. Comparison and analysis are also provided between our calculated results and that obtained from the two phase friction multipliers proposed by Lockhart Martinelli, Chen Kalish and Kaiser Peppler.
