Abstract : Number of blades is one of the major parameters affecting the performance and stability of compressors. The number of blades usually determined using blade spacing (the distance between two blades). This study has been devoted to estimating the change of performance parameters of rotor 37 as a result of number of blades change. The results of this study obtained using the CFD code “NUMECA Fine/Turbo”. This CFD code is a steady, quasi-three-dimensional Reynolds Averaged Navier-Stokes (RANS) solver. Presented a comparison between three turbulence models (k-Epislon, Spalart- Allmaras and Blatwin-lomax) with experimental data. Spalart-Allmaras turbulence model is used mainly for calculations. The results are presented for three rotational speeds and three values of number of blades. Provided an analysis of number of blades effect on rotor pressure ratio, efficiency, loading coefficient and work. The obtained results verified using an existing experimental and published data.

Keywords : Number of Blades, Compressor, Rotor 37, Performance Parameters.
