The main objective of this work is to improve the performance of multi stage mixed flow submersible pump. This pump highly depends upon the complex configuration of the Bowl-Impeller Interaction and the flow behavior of water in the same region. A commercial Computational Fluid Dynamics (CFD) code, namely ANSYS Fluent V13.0 with a k-ε Realizable turbulence model was used to study the effects of Bowl-Impeller Interaction. An extensive approach is tried to predict the flow behavior of the pump. The space between the bowl and impeller is called as “Axial gap”. In the existing model the axial gap between the bowl and impeller is 17mm. In this paper, the investigation of Bowl-Impeller axial gap for six different models is varied from 2mm, 5mm and 10mm (Increase and Decrease) to predict the performance of the pump. The numerical results are compared with the Best Efficiency Point (BEP) of experimental data. For the present pump, 2mm Decrease Bowl-Impeller axial gap model performs better comparably to the other models. It performs up to 2.35 % of efficiency from the existing model
