| Abstract: | According to the characteristic of water jet propulsion axial-flow pump with front guide vane,the mathemat-ical model of pump with front guide vane in 3D unsteady flow is established.On the basis of axial-flow pump radial variable circulation distribution design method,the parameter selection principle such as circulation distribution,meridional velocity,.blade density,blade thickness radial distribution,airfoil profile and design process which is suitable for axial flow pump with front guide vane.This paper can provide guide for engineering application. |
| Keywords: | front guide vane water jet propulsion variable circulation distribution axial-flow pump |
