This paper focuses on the analysis of axial space between
rotating blade rows and the stationary one in an axial-flow
compressor in function of the geometry and aerothermodynamic
considerations. The axial distance is determined by the
mathematical model obtained using design variables of
rotating blade rows and the stationary blade rows or
determined axial distance values.
In this work, the analysis also consider the
transition plane between rotating blade row and the
stationary one, where outlet values for the rotating blade
row is considering the same for the inlet values in the
stationary blade row. Under this consideration the study was
carried out for values of aerothermodynamic design, they
were evaluated to identify which ones are more accurate to
define a physical distance between rows. The results were obtained using the mathematical model and
compared with data of axial flow compressor in one plane.
There are maximum differences about a 25% between calculated
distance and experimental data, for intermediate stage of
axial compressor.
Conclusions show that mathematical model can be
applied for conditions of preliminary design of space
between rotating blade rows and the stationary one in their
middle zone.
