description: The essence of this work consisted in the calculation and design of a multi-shaft four-section centrifugal compressor. This calculation consisted of several parts, such as gas dynamic calculation and calculation of compressor parameters. In the gas-dynamic calculation, the parameters of the efficiency of all stages, head, Mach number and flow rates were found. In the calculation of the compressor parameters, the basic geometric values for the design of this compressor were obtained. Since there was a very high pressure at the last stage of this multi-shaft four-section compressor, it is necessary to design a combined seal, which was calculated theoretically. Subsequently, an experimental calculation of this compaction was carried out in the ANSYS software package, in which the work was carried out in such modules as Geometry, Icem CFD, CFX. In the Geometry module, the geometry of the seal was built, the part was extruded and the surfaces were marked. In the Icem CFD module, it was necessary to generate a mesh for the combined compaction. In CFX, it is necessary to set the input and output boundary conditions, set the values of the rotating parts.
