説明
The study concerns the visual observation of the formation of the bubble-depleted region in the frontal vicinity of a large bubble injected in a swarm of otherwise uniformly dispersed small bubbles. For this purpose, experiments are conducted exclusively in a two-dimensional column to ensure the distinct appearance of a single cap throughout its rise in the swarm over a wide range of gas hold-ups. Other parameters, including physical properties of the gas and liquid phases and sizes of the two classes of bubbles, are either fixed or of limited ranges. The specific focus is on the measurement of the size of the bubble-depleted region
