| Abstract: | In this paper the Kriging model was applied to the aerodynamic optimization design of the vaned diffuser for a high speed centrifugal compressor.The objective of the optimization was to redesign the blade profile of the vaned diffuser that assures,at the design operating condition,the maximum isentropic efficiency of the stage composed of impeller and diffuser with the diffuser's outlet pressure not falling down.The Kriging model accelerated the design process remarkably.Compared with that of the original,the performance of the optimized diffuser was improved a lot. |
