摘要：
The sizes and rise velocity of bubbles in a stationary liquid in an inclined channel with a circular cross-section at different gas flow rates through a capillary were determined (3.0-5.5 ml/min). The size and velocity of gas bubbles were studied by shadow photography. It is shown that in the range of channel inclination angles 40-60 degrees, the formation of stable bubble structures-clusters consisting of bubbles of the same size (1.5-1.8 mm) - is possible. In regimes without the formation of chain clusters, the average diameter of gas bubbles increased (2.0-2.2 mm) due to their coalescence.
