Description
Summary:The paper presents the results of one of the stages of creating a model of assessing and forecasting the operating characteristics of a transonic compressor due to erosive wear. A numerical model of a transonic compressor stage is constructed and verified to substantiate its applicability in calculating various degrees of blade erosive wear. The article contains a review of the basic approaches for turbulence simulation, their application area and basic features connected with 3D-flow simulation in turbomachines. The parameters and settings of the numerical model are shown. The CFD-obtained results are presented and compared with the experimental data and results of other researchers. By this comparison the accuracy of the CFD-obtained overall performance and the quality of modeling local processes are determined. Possible ways of improving the models accuracy are also specified.
