Summary

The 4th generation model of the known TU SPb Universal modeling programs for gas dynamic design were perfect enough to predict design point efficiency with accuracy about 2,5% if a single set of coefficients was applied. To raise accuracy of calculations to 1% or less different sets of empirical coefficients were necessary for stages with different flow rate and work coefficients. The proposed text is focused on scientific background and realization of model improvements that leads to accuracy about 0,5% of design efficiency prediction with a single set of empirical coefficients for all types of stages and compressors. Samples of application are given.
