Abstract
Centrifugal pumps are widely used in many industrial applications and they are usually considered the main component of the system, as is the case of pumps for petroleum production through the Electrical Submersible Pump. The comprehension of the components behavior is indispensable for the development, and improvement of be more efficient, reliable and economical systems. However, the analysis of the internal flow of a centrifugal pump is highly complex. This analysis and the determination of the operational conditions can be supported by numerical simulation, using Computational Fluid Dynamics (CFD) techniques, which allows the prediction of flow behavior with off-design conditions, providing reduction of costs and time. This paper presents numerical simulations performed in the computational model of a pump impeller in order to obtain the preliminary results of the numerical models applied by the ANSYS CFX code. With the results, it was possible to obtain the impeller head characteristic curve and compare it with the analytical curve obtained, also making an evaluation of the flow through the study of meridional profiles for the selection of the pressure conditions and the velocity inside of the impeller.
