description: This paper describes the design of a low-flow centrifugal three-stage compressor using the NZL method and the subsequent optimization of the intermediate stage impeller using specialized ANSYS WORKBENCH modules. The main characteristics of the centrifugal compressor were obtained, as well as the operating process parameters in the control sections of the flow part, and a one-dimensional and viscous quasi-three-dimensional calculation of the installation was considered. Calculation and design of a centrifugal compressor was carried out based on technical specifications and recommendations. The calculation of the flow part was carried out using the NZL method, the calculation was carried out using the obtained data in the ANSYS program, the obtained data were compared and the transition to optimization of the intermediate stage impeller was carried out, gas-dynamic and geometric parameters were obtained and compared before and after optimization. A gas-dynamic calculation of the optimized flow path elements was carried out in the ANSYS CFX program, based on which conclusions were drawn about the accuracy of the applicability of such optimization methods for this installation and compressors in general.
