Abstract

Centrifugal pumps are widely used in a myriad of applications, such as industry, agriculture, and residential, among others. These devices are often used nonstop, thus playing an important role in energy consumption. Therefore, the improvement of the design of these devices results in dramatic cost reduction. The present work used Computational Fluid Dynamic (CFD) as a tool for designing the impeller of a turbopump. The main objective was to obtain the maximum head provided to the fluid being pumped. The Ansys® software was used to obtain the simulated results. The turbulence model used was the κ-ε. In this work the interaction between the impeller and the casing was not considered. Both the geometric parameters and the number of blades of a predefined impeller configuration were modified to obtain the maximum head. A 12% increase in the head provided by the impeller was obtained when the number of blades was increased from 6 to 13.
