摘　　要：利用质量守恒、动量守恒和能量守恒方程,采用汽泡动力学和两相流的经验处理技术,导出了一个计算汽液两相流在单管内向下流动的临界热流密度(CHF)半径验关系式。其理论计算值与实验值有很好的一致性。A mechanistic Modeling of Critical heat flux (CHF) in single-tube downfiow boiling at low qualities is presented. The developed model is based on basic conservation equations bubble dynimic and two-phase flow empirical correlations. The predication are in good agreement with the experimental data.
