摘要
对管径15 mm,管长6 m的有机玻璃管,在两种不同的向上倾斜角度(15°、30°)下,同向通过的气水两相流流型转变进行了分析,列出相应的转变准则关系式。结果显示,弹状流向泡状流转变界限的实验值与计算符合较好,间歇流向环状流的转变界限在低液体流速下符合较好。
The transition analysis of co-current air-water flow patterns was conducted and the transition criterion correlations were presented with two inclination angles (15°,30°) in a 15 mm diameter, 6 m long acrylic pipe installed on an inclinable trestle. The results showed that the experimental results made a good agreement with the theoretical results of the transition boundary between slug flow and bubble flow. However, the good agreement results between slug flow and annular flow were given just under low liquid flow rate.
