Methods for calculating supersonic centrifugal impellers and recommendations for their design by numerical methods

Centrifugal compressors are widely used in various industries, in metallurgy, chemical, oil and gas, aviation and others. The obsolescence of some of the existing compressors and the program of import substitution and development of the aviation industry announced by the President and the Government of the Russian Federation creates an urgent problem with a promising method and methodology for designing centrifugal compressors. To design a centrifugal compressors using the listed methods, it is necessary to correctly configure the boundary conditions of the solver and have a grid model that meets the solver requirements. The article presents a description of the results of similar works and an analysis of these results. To conduct our own study of the selected object, where all the necessary data are available in open sources, its digital and grid model was built and a series of calculations were carried out on various grid models, the analysis of the calculations was performed and its results were presented. The validation of the numerical experimental method was carried out, the error of the numerical experimental method was established.
