Obtaining the maximum permissible gas content at the inlet to the ESP by computational fluid dynamics modeling

Abstract

Methods for increasing the operation stability of the electrical submersible pump (ESP) are listed. Examples of computational fluid dynamics (CFD) applications for designing and studying the flow part of the pump are given. The results of mesh convergence study, Pump performance curve, and dependences of head and hydraulic efficiency on gas content at the inlet, obtained by CFD methods, are presented. The results of CFD modeling are compared with experimental curves.
