New types of cavitation generators have been developed to increase the efficiency of production well treatments in order to increase their flow rate. The general regularities of flooded jet outflows from the Ventury-type nozzles for borehole conditions were revealed by analytical and numerical methods. Numerical modeling of multiphase flows passing by applying the finite element method was performed on the Star-CCM+ platform (Siemens PLM Software). The article describes the applied hydrodynamic calculation models, boundary conditions and the choice of solver parameters. A model was obtained that makes it possible to predict the difference in resistance at which cavitation occurs and the place of its occurrence. In the future, when conducting comprehensive researches, this information will be used to optimize the shape of cavitation generators, depending on the purpose of the technological process. The results obtained were verified by practical testing in natural conditions.
