| Abstract: | By using NUMECA CFD software,based on the numerical simulation of the movement to the axial fan in the pre-rotation angle of-30°~30°range,the results show the overall performance variation of the fan,distribution of blade load and flow loss,moreover,flow parameters along the leaves of high and circumferential distribution,the affect that the pre-rotation regulation on the fan performance is analyzed in detail.These could provide reference for the leading leaf design and pre-rotating devices regulation. |
