IMPROVEMENT OF QUALITY OF MA THEMA TICAL MODEL OF HEAD OFLOW-FLOWSTAGES OF CENTRIFUGAL COMPRESSORS
A new mathematical model for determining coefficients of internal and theoretical head at the design mode of operation at designing of low-flow impellers and stages of centrifugal compressors has been developed. High quality of the mathematical model has been checked up by means of comparison with experimental data and results of numerical experiment on digital twins, which were not used in model making, and provides a high quality of design calculations.
