The article presents the results of the study of cavitation processes in technological equipment related to analytical phenomena that are accompanied by cavitation. One of the important factors accompanying cavitation processes is hydrodynamic luminescence. For the practical study of the mechanisms of hydrodynamic luminescence, an experimental stand based on a hydrodynamic cavitator was developed and manufactured. This stand allows to investigate the flow characteristics of the cavitator, to observe and make photo and video fixation of the phenomenon of hydroluminescence in the flow of liquid or gas-liquid mixture, for which an ejector mixer was used. Based on the results of processing and analysis of experimental studies, a conceptual model of the stages of origin and development of the cavitation process and the accompanying effects is built.
