摘要: 利用俄罗斯IL-76MDK失重飞机对失重条件下方形截面(12mm×12mm)管道内气/液两相流动进行了实验研究,观测到失重条件下气/液两相泡状流、弹状流和环状流等三种主要流型,同时得到了气、液两相介质的流量、温度和实验段内压力等结果,分析了失重条件下方形截面管道内气/液两相流型转换的条件.Abstract: An experimental investigation of the air-water two-phase flow in a tube with a12mm×12mm square cross-section is performed under reduced gravity on board IL-76MDK Russian airplane. Three main flow patterns of the gas-liquid two-phase flow under reduced gravity conditions are observed. The flow rates of the air and water phases, the water temperature and the pressure inside the test section are obtained. The flow pattern transitional criteria of the gas-liquid two-phase flow at reduced gravity are also discussed.
