The paper presents the results of computational model verification in the ANSYS CFX program complex based on the obtained experimental data of K-50-1 axial compressor stage. The obtained data is analyzed while computing it with the help of different turbulence models and various mesh sizes of the computational domain. The computational and experimental data are compared with each other. The method of computational domain fragmentation into finite elements is described. The authors give recommendations for implementing both the analyzed turbulence models and the mesh sizes of the computational domain for computing axial compressor stages.
