The article is devoted to computer modeling of the process of cavitation in liquid
mediums. The experimental researches of the regularities of the cavitation process was
conducted, dependences of changes in the parameters of the process efficiency on the
concentration of the solution and the frequency of vibration are shown. A solid– state model of
a laboratory vibration resonance electromagnetic cavitator in SolidWorks 2016 Educational
Edition software system was created. Based on the modeling of the cavitation process, the main
hydrodynamic parameters are defined: temperature change, static pressure and flow velocity
in the laboratory chamber.
