FRACTAL STRUCTURE OF BUBBSTON CLUSTERS IN WATER AND AQUEOUS ELECTROLYTIC SOLUTIONS

Experiments confirm that clusters of microscopic bubbles (bubbston clu sters) arise in a liquid as the result of a coagulation of elementary microbubbles (bubbstons). Their fractal dimension and average radius h ave been determined for water and for aqueous solutions of electrolyte s and coagulants. The fractal properties of the clusters depend on the concentration of the electrolyte. It is shown experimentally that the re is a relationship between the threshold for optical breakdown in a liquid and the number density of clusters.
