  • Approaches about preliminary parameters deign and 3-D modeling of high-speed small flow rate centrifugal compressor were presented,and corresponding FORTRAN code was developed.In order to verify the feasibility of the approaches,an impeller based on Krain's impeller was modeled with its camber line optimized by curvature control.The blade of the impeller was matched with S-shaped blade of good aerodynamic performance.After analysis of CFD results,the redesigned impeller achieved isentropic efficiency of 93.9% and total pressure ratio of 4.794 on design mass flow rate,and the error was 0.24% and 2.14% respectively compared with Krain's impeller.Results show that the approaches and the code are valid for rapid impeller design.
