Abstract When the traditional impeller axial streamline segmenting method is implemented in the hydraulic design of centrifugal impeller, it requires repeating choosing the values and comparing their suitability, resulting in the accumulated errors. Therefore, it is slow and with low precision. In order to obtain higher efficiency and accuracy, this article brings out a mathematical method by geometric analyzing and the algebraic description for the progress of segmenting axial streamline. It finally gives the formulas that can be used in computer programming.
