We conducted the experiments with ultrapure water and silicon oils to explore dynamics of these bubble configurations and to compare it with a theory1,2. The three dimensional path of bubbles during the rise was reconstructed from double side view using high-speed cameras. The influence of particle separation and Reynolds number will be presented. Interestingly the small variance of bubble sizes has shown to be responsible for a scatter of the data obtained in ultrapure water3. It should be noted that an influence of surfactants on the structure of bubble aggregates and their stability remains almost unexplored experimentally at the mesoscale so far.
