| Abstract: | In view of the case that the calculation accuracy of existing quasi three dimensional method for the flow calculation within centrifugal impeller with low specific speed is still dissatisfactory, the singularity distribution method is adopted to calculate such flow field. The feasibility of this method is verified by an engineering illustration and, moreover, it is shown by the calculation process that this method is simple featuring quick obtainable and highly accurate results. |
