| Summary: | The mathematical model underlying the program for calculating and designing axial compressors is
presented. The process of calculating the pressure loss in the elements of the axial compressor stage
flow path is described. The loss coefficient consists of losses on the limiting surfaces, secondary losses
and profile losses. The effect of roughness on the pressure loss is taken into account by introducing the
corresponding empirical coefficient. An algorithm for calculating the blades and vanes angles of the
impeller and the guide apparatus is presented by calculating the incidence angle and the lag angle of
the flow. The flow lag angle is the sum of the lag angle of the flow on the profile and the lag angle due
to viscous flow on the limiting surfaces |
