description: The aim of this work was to study various configurations of labyrinth seals of a centrifugal compressor cover disk In this work, seventeen different variants of the execution of the labyrinth were investigated. Five seal configurations were selected for the job, two straight-through and three staged. After constructing 3D models of the seals, the gas flow in the labyrinth seals was numerically simulated, and the characteristics of the gas flow in the seals were obtained. To calculate the gas flow rate through the seals, formulas were chosen that consider the geometry of the gas flow in a stepped labyrinth seal and which consider the incomplete transformation of the kinetic energy of the gas in direct-flow seals. Seal flow rates as well as leakage and friction rates were calculated. As a result of the analysis carried out, the seal configuration was established with optimal performance and greater efficiency.
