| 摘 要： | 为预测含内热源多孔介质通道内流动沸腾的两相阻力压降，以Ergun方程为基础，定义了多孔介质通道的Chisholm参数Y和全液相折算因子Φl0。通过理论分析和实验数据测量，明确了出口质量含气率xe、质量流速G和小球直径d等对参数Y和Φl0的影响，并提出1个Lockhart-Martinelli（L-M）类型的两相阻力压降关系式。与文献中的其他公式相比，本工作提出的公式对实验结果能做出更好的预测。

| Abstract: | Based on Ergun equation, the Chisholm parameter Y and two-phase multiplier Φl0 for porous media channel were defined to predict two-phase pressure drop during flow boiling in porous media channel with internal heat source. Effects of exit quality xe, mass flux G and particle diameter d on parameters Y and Φl0 were identified by theoretical analysis and experimental measurements. A Lockhart-Martinelli (L-M) type correlation for predicting two-phase pressure drop was proposed and it can make more reasonable predictions to experimental results than other correlations available in literature. |
