![]() The improved impeller design exhibits a considerable increase in hydraulic efficiency compared to the initial design. The optimum values of the above that maximise the hydraulic efficiency at the BEP are then derived using a stochastic evolutionary algorithm software. ![]() Parametric studies are conducted to examine the influence of several design parameters, like the blade length, inlet height, leading edge inclination, cambering, and mean line curvature. ![]() The possibility of improving the design and increasing the hydraulic efficiency of a centrifugal pump impeller is investigated, with the implementation of advanced numerical tools and experimental data from a laboratory model. The final impeller can distribute load equally with the characters of high efficiency and excellent cavitation performance. The impeller is modelled in Solidworks 2012 software and CFD analysis is done using fluid flow simulation package. This method which applies the meridional velocity of direct problem result to inverse problem, can make up the deficiency of traditional design method by using one-dimensional flow assumption. Vane profile of the impeller is generated using point by point method. Theories on pump characteristics are studied in detail.
