description: This work is devoted to the implementation and verification of the methodology for calculating leakage losses in the gap between the blades of a semi-open centrifugal impeller and the housing. Tasks that were solved during the research: 1. Analysis of various leak loss calculation methods 2. Implementation of the selected techniques 3. Verification of mathematical models by comparison with experimental data A database of various methods for calculating losses in the gap between the ORC and the compressor housing was collected. These techniques were later introduced into the mathematical model of the Universal modeling Method, which was developed at the Department of Compressor Engineering. The results obtained during the calculation of the mathematical model were analyzed and compared with experimental data obtained during the test of the TKR 140E centrifugal compressor in various operating modes at the NPO Â«TurbotechnikaÂ» stand. Based on the results of the comparison, it can be concluded that the Simonov loss calculation model looks more physically justified and plausible. The effectiveness of the application of a particular technique can be said only after verification of each model based on the results of a larger amount of experimental data.
