| Abstract: | The mathematic model expressing 3-D shape of the inlet passage of a large pumping station is established and then the flowfield in various passages with oblique pump set are calculated with finite clement method. The optimization object of the varied passages is that the nonuniformity of the velocities at the outlet section of the passage is minimum, for the sake of which the optimum passage shape is determined with the given main linear dimensions of the passage. |
