| description | The analysis of implementation features of the mathematical model of a transonic centrifugal compressor
stage with an input guide vanes (IGV) and a semi-open axial-radial impeller has been carried out. The
flow study is performed using the Navier-Stokes equations, closed by the Shear Stress Transport (SST)
turbulence model. The simulation is performed for the regulation mode at a reduced rotational speed
of 28,076 rpm and two IGV angles of rotation in a wide mass flow range. In the course of the study,
the parameters of the design model (density of the mesh, inter-mesh connection of the two elements of
the flow path) are considered and the effect of the tip between the impeller blades and the body on
the gas-dynamic characteristics of the stage is evaluated. According to the results of the study, the most
significant parameters that affect the accuracy of the results obtained are established |
