| Abstract: | The design procedures about a centrifugal compressor of small mass flow rate with splitter blade are described in this paper. The main design parameters about the impeller are mass flow rate 0.215 kg/s, rotor speed 95000 r/min and pressure ratio 1.8. A centrifugal compressor design system is introduced briefly, which includes the optimum design module, the performance simulation module and the blade design module. Three-dimensional Navier-Stokes equation is used to calculate the centrifugal compressor performance at design point. The calculated results illustrate that the design aims have been realized. |
