COMPUTATION OF HYDRODYNAMIC CHARACTERISTICS OF WATER FLOW IN ELECTRICAL SUBMERSIBLE PUMP

Abstract

The electrical submersible pump (ESP) systems play an important role inthe industry and many engineering applications. It is frequently used in the drinking waterpurification units for lifting water from well. The centrifugal pump is the most important partof ESP systems. In the present work, a simulation have been carried out using ComputationalFluid Dynamic CFD techniques and commercial software based on the finite volumemethod, ANSYS® CFX® Release 11.0. The results of the simulations include the pressurefields, velocity field, and velocity vector obtained to the internal flow in the impeller anddiffuser channels of a centrifugal pump at flow rate 0.005m3/s. A stationary flow withconstant boundary conditions is proposed. A comparison between the simulation of thepresent work and the head capacity of the performance curve that obtained practically wasperformed and showed satisfactory agreement.
