The paper presents a photographic analysis of the break-up of gas bubbles flowing out of the outletsof a self-aspirating disk impeller. It was found that bubbles detached from the interfacial surface mostoften disintegrate to form several daughter bubbles. Further in the work, the population balance modelwas verified for several formulas describing the bubble break-up rate. It has been found that a good fitto the experimental data is provided by the formula given by Laakkonen for 5 daughter bubbles. Thepossibility of using the Monte Carlo method to model the bubble break-up process was also determined.For this method, a good agreement of results was achieved for the division into a maximum of 10daughter bubbles. In the case of this method it was also found necessary to use the function of break-upfrequency at a higher rate for smaller bubbles.
