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.
