description: The studies object is the low-and medium-flow stages of centrifugal compressors. The work purpose is verification the results of calculating the gas flow using the NUMECA Fine/Turbo software package with experimental test data of 3 medium-pressure medium-flow stages, differing in the type of diffuser, and 2 low-flow stages of a centrifugal compressor. Three-dimensional models of the blades and the flow parts meridional contours were created in the process. As a result, comparisons of the calculated and experimental gas-dynamic characteristics were obtained, the satisfactory accuracy of the calculation was shown, and the conclusion was made about the feasibility of implementing the computational gas dynamics method implemented in NUMECA Fine/Turbo, aimed at solving turbomachine engineering problems. The use of the computational gas dynamics method will reduce the research and development work cost. Further accumulation of knowledge on verification will improve the calculations accuracy.
