| Abstract: | A numerical method to calculate the internal flow in axial-centrifugal combined compressors having complex flowpath has been obtained in this paper. Considering the viscosity and the spanwise mixing, two types of combined compressor have been calculated. Based on the results, the effects of the viscosity and the spanwise mixing to the flow have been discussed, the flow characteristics and aerodynamic performances of these two compressors have been analyzed and compared in detail, and some suggestions have been made. This method can be contributed to establish a design and analysis system for advanced axial- centrifugal combined compressor. |
