“…In the work of Xu et al [9] and Liet al [10], the orthogonal table method was used to optimize the centrifugal pump performance, which improved efficiency and reduced critical net positive suction head (NPSHc) by 3.09% and 1.45 meters, respectively. Sekino et al [11] performed the optimization design for the double suction centrifugal pump with the help of design of experiments (DoE) and computational fluid dynamics (CFD). The results showed a 4% rise in efficiency.…”

The design and off-design performance of a centrifugal pump largely depends on geomechanical parameters. This study aims at enhancing the performance by optimizing three geomechanical parameters of impeller-volute interactions. The present optimization is carried out using the Taguchi method combined with a numerical approach. A comparison between the base and optimized pumps is presented under the design and off-design conditions based on numerical and experimental analyses. The numerical results reveal that, compared to the base pump, the optimized pump shows the improved performance through uniform pressure distribution in the impeller, the reduced low-pressure region towards a blade’s leading edge, and the stable total pressure at the impeller-volute interaction zone. The experimental results suggest that the optimized pump covers a wider range of operation, and its best efficiency point (BEP) is 10%, 5%, and 12% higher in flow rate, head, and efficiency, as compared to the base one.

In this study, Computational Fluid Dynamics (CFD) Analysis is used to investigate the flow in the centrifugal pump impeller using the ANSYS-CFX. Impeller is designed for head of Keywords CFD, vertical pump, head, impeller, volute casing IntroductionPump is designed as per API 610 standards. Modelling of impeller, volute geometry and all pump components is done in software CREO 3.0 by assuming the required duty parameters. Double suction impeller is designed to meet required head and flow at operating speed. Double volute casing is used to transfer fluid from inlet to outlet pipe.Nowadays the use of CFD plays an important role in fluid mechanics. Due to the progress in computer capability and numerical methods, the design analysis of centrifugal pumps by using 3D-Navier stokes program or CFD software has become easy. The impeller could be redesigned if the final result from the CFD differs from the designed value [1].Number of researchers has studied the application of CFD in fluid mechanics and turbo machinery over the years [1][2][3][4][5][6][7]. However, there are few researchers used this CFD tool to predict the performance of pump impeller. Until now, there have been only three works carried out by Rajendran and Purushothaman
