New Design Method for the Formed Suction Intake in Axial-Flow Pumps with a Vertical Axis

A concept of the formed suction intake design obtained with an algorithm for vertical axial{ ow pumps is presented. The design methodology is a part of works conducted within project no. N N513 460240 supported by the Polish National Science Center. The proposed procedure is used to optimize intakes. The results of steady ow numerical computations in the suction intake as well as applications of the design optimization in the aspect of ful lling two objective functions are discussed. The objective functions given by the authors concern the optimal in ow of the uid into the impeller.
