| Abstract: | The aerodynamic characteristic and performance comparison of a centrifugal impeller before and after its blade near leading edge thinned down are calculated using CFD method. The detail of flow field is compared and analyzed, and the total performances before and after blade thinned down, such as quality flowrate, efficiency, axial thrust and efficiency, are also compared. |
