| Abstract: | A method for calculating the variation of flow channel section of a centrifugal impeller along its flow path was obtained through a geometric analysis and strict mathematical deduction of the impeller flow path, thus providing an analytical solution of the flow channel section. In a specific engineering case a design method based on the above approach was employed followed by an adjustment of the impeller design. With the elimination of gas flow separation phenomenon and the realization of higher impeller efficiency one can conclude that relatively good results have been achieved. |
