摘要
提出了热力学非平衡两流体临界流六方程模型，并对汽泡增长方程，流体状态方程和基本结构关系式进行了改进。利用本模型成功地预测了本试验中的实验结果，并利用前人的实验数据验证了其通用性。此外还利用本模型分析了在临界流动中各参数的变化及破口通道长径比、破口通道直径，起始汽泡密度和汽泡直径对两相临界质量流速的影响。
In the papaya non-equilibrium two-fluid critical flow model with six eq-nations was devel-oped ,with improved bubble growth equation, fluid status e-quation as well as constitutive relations. The model prediction agreed wellwith the experimental data in this paper and other experimental data, The in-flounces of the ratio of the break's length to its diameter, break's size, i-initial bubble delsity and initial bubble diameter were andalyzed by the mode-l.
