| Abstract: | According to the blade external flow theory, speed distribution of blade surfaceshown by transformation coefficient has been obtained by means of conformal transforma-tion and series developmtent,thus giving mathematic model of hydrodynamic moment ofadjustable blades of axial pumps, and reliability study. Finally, the calculation has beenmade of hydrodynamic moment of adjustable blades of a certain pump. The study showsthat the method is reliable and its result is satisfactory. |
