Analysis of the Efficiency of Elementary Grids of Axial Compressors Based on the Data of Flat Grid Purges

Abstract

Published data on flat grid purges allow to evaluate the efficiency of blade devices with different kinematic scheme of stages and design parameters. The authors present the main provisions of the calculation program algorithm and some results of numerical analysis of the efficiency of flat grids of axial stages with different combinations of design parameters. The content of the article and the computer program are addressed to people who are improving their knowledge of gas dynamics of axial compressors. Some of the results may be of interest to specialists working professionally in this field.

“…The authors present the results of verification of their model for two axial compressors. In works [15], [16] the code of the center line of an axial compressor operating in noncalculating modes is described for specialized engineering software that is developed for the analysis of the entire gas turbine engine. A generalized methodology for losses simulation on the midline of the axial compressor has been developed.…”
