| Abstract: | The complex flow structure within the region of a centrifugal compressor's impeller and diffuser vanes has been analyzed by fully unsteady three dimensional viscous calculation on the basis of TVD code. More details of the flowfields of the impeller and diffuser have been explored by carefully calculation with a super computer. The time-averaged results of fully 3D unsteady calculation revealed that the impeller discharge wake flows into the diffuser vanes like travelling waves, but it is immediately dissipated before it reaches the vanes' throat. A comparative test has been carried out. The measured data can be used to verify the calculated results qualitatively. |
