摘　　要：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。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.
