The influence of geometry and operating conditions of the centrifugal compressor stage on the radial gas force is determined on the basis of the theoretical method and calculation program using experimental boundary conditions. © Allerton Press, Inc., 2011.

The influence of the clearance between the case and blade ends of the semi-open impeller on the centrifugal stage characteristics is considered using the experimental data and numerical calculation results. © Allerton Press, Inc., 2011.

We present the results of the numerical simulation of a flow and radial pressure distribution in the lateral clearances of the semi-open axiradial impeller of the centrifugal compressor with the use of the FlowVision and Fluent software. The results of the numerical analysis were compared with the known experimental data. © 2012 Allerton Press, Inc.
