During the present research of the flow characteristics of refrigerant in adiabatic capillary tubes , a drift flux model of two - phase flow was established and the influence of metastable phenomenon was considered . the flow characteristics of refrigerant were analyzed with the program developed in this research . an experimental system for the adiabatic capillary tubes testing was set up . the results show that the theoretical model fits the experimental data well 在对绝热毛细管内制冷剂的流动特性进行研究的过程中,运用两相流漂移模型,并考虑制冷剂在实际流动中存在的亚稳态,开发了绝热毛细管内制冷剂两相流的数值计算程序,对毛细管内制冷剂的流动特性进行了分析;搭建了毛细管两相流实验装置,并将计算结果与实验数据进行比较,结果吻合的较好。
