Abstract

Based on analysis of information sources was found that dimensionless complexes - numbers of cavitation, Reynolds, Weber - are used to characterize the intensity of the development of cavitation phenomena.  It was established the critical value of the Reynolds criterion (Reqr = 32,500) in the case of the treatment of the aqueous medium in a hydrodynamic jet cavitator, which will enable to regulate the intensity of the development of cavitation and to avoid its negative consequences.
