| 摘 要： | 本文给出了一个既考虑热力学非平衡的影响,又考虑汽、液相间相对速度的毛细管内带有汽化过程的两相流数学模型。模型计算结果与试验数据的一致性及计算程序的实用化处理表明,它不仅可用来分析制冷剂在毛细管内的流动机理和特性,还可应用于小型制冷系统设计中毛细管几何参数的选择及系统的参数匹配。

| Abstract: | In consideration of the thermodynamic non-equilibrium phenomenon during vaporization and the relative velocity between the liquid and vapor, a model for two-phase flow in capillary tubes has been developed. Good agreement is found between the experimental results and the calculating data. The practical handling of the program shows that the model can be used for the selection of capillary tubes in the design of refrigerating systems and the parameter matching of the systems. |
