description: This work is devoted to the study of various versions of the flow part of free-vortex pumps on their energy and cavitation characteristics and comparison between them to identify the best option. Tasks solved in the course of research: 1. Literature review to study the design features of FVPs. 2. Simulation of variants of flow parts on the basis of the literature analysis. 3. Analysis of results of modeling for different variants of flow part of free-vortex pumps. 4. Analysis of simulation results for different variants of flow part of free-vortex pumps. As a result of work comparison of 3 basic designs of FVP has been carried out. The analysis of influence of design on pressure and cavitation characteristics has been carried out. The received results allow choosing the most optimal variant of design when using a free-vortex pump. Also, in work two-phase flow of a liquid is investigated. The areas of possible erosion damage for different values of cavitation margin are determined. Strength calculations using SolidWorks Simulation and Ansys Mechanical packages have been performed.
