【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两相流的数值计算,对毛细管内制冷剂的流动特性进行分析;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。更多还原

【Abstract】 During the research of the flow characteristics of refrigerant in adiabatic capillary tubes, a drift flux model of two-phase flow is established and the influence of metastable phenomenon is considered. A program is developed. The flow characteristics of refrigerant were derived and analyzed with this program.; An experimental table for the adiabatic capillary tubes research is established. Through compare between experiment and calculation, consistency is conceived.更多还原
