description: The purpose of the work is to carry out a numerical calculation of the gas flow using the Ansys software package to determine the effect of changing the geometry of the lateral clearances between the rotor and stator on losses and leaks, as well as to evaluate the complex (1 + Î²tr + Î²pr) and analyze the results. In the process of work, a three-dimensional model of the blades and meridional contours of the flowing parts of the steps were created, a block-structured mesh was built separately for each element of the step. As a result of the study, the calculated gas-dynamic characteristics of the stage were obtained, and the satisfactory accuracy of the calculation was shown. The use of the computational gas dynamics method will reduce the cost of research and development work. Further accumulation of the calculated knowledge base will improve the accuracy of calculations.
