在倾斜和摇摆条件下，对矩形通道（40 mm ×3 mm）内泡状流的局部参数分布特性进行了研究。竖直条件下，“核峰”和“壁峰”分布形式在实验中都有出现；在液相折算速度较小和气相折算速度较大的工况下，局部参数呈现“核峰”分布。倾斜条件下，通道上方的峰值随倾斜程度的增加而变大，而通道下方的峰值随倾斜程度的增大而减弱，直至消失。摇摆条件下，当摇摆角度与倾斜角度相同且逐渐增加时，局部参数的分布主要体现在通道上方峰值的增加，但不改变出现峰值的位置，相应地，通道下方的峰值略有减少。不同摇摆工况下，摇摆振幅越大，摇摆运动的程度越剧烈，其对相同倾斜角度的峰值的影响也越大。

Characteristics of local parameters of bubbly flow were investigated in rectan‐gular channel (40 mm × 3 mm) under inclined and rolling conditions .Under vertical condition ,the distribution type ‘wall peak’ and ‘core peak’ are observed ,and ‘core peak’ exists w hen the liquid superficial velocity is low and the gas superficial velocity is high .Under inclined condition ,the peaks of two distribution types get strengthened at the top of the channel ,and weakened at the bottom .Under rolling condition ,the peaks of two distribution types get strengthened compared with the same angle under inclined condition when the angle is getting larger .The influence from rolling motion gets stron‐ger on the peak of two distribution types when the rolling movement is more violent .
