“…Coupled with a modified k-ε turbulence model by considering the viscosity of the liquid phase and the compressibility of the gas phase, the gas/liquid distributions versus different attack angles were obtained. Caridad et al [108,109] studied ESP impeller performance handling water/air mixtures using CFD simulation. Applying two fluid models in 3D CFD simulations, the pressure and velocity fields, as well as the gas phase distributions ( Figure 13) were obtained.…”

As the second most widely used artificial lift method in petroleum production (and first in produced amount), electrical submersible pump (ESP) maintains or increases flow rate by converting kinetic energy to hydraulic pressure of hydrocarbon fluids. To facilitate its optimal working conditions, an ESP has to be operated within a narrow application window. Issues like gas involvement, changing production rate and high oil viscosity, greatly impede ESP boosting pressure. Previous experimental studies showed that the presence of gas would cause ESP hydraulic head degradation. The flow behaviors inside ESPs under gassy conditions, such as pressure surging and gas pockets, further deteriorate ESP pressure boosting ability. Therefore, it is important to know what parameters govern the gas-liquid flow structure inside a rotating ESP and how it can be modeled. This paper presents a comprehensive review on the key factors that affect ESP performance under gassy flow conditions. Furthermore, the empirical and mechanistic models for predicting ESP pressure increment are discussed. The computational fluid dynamics (CFD)-based modeling approach for studying the multiphase flow in a rotating ESP is explained as well. The closure relationships that are critical to both mechanistic and numerical models are reviewed, which are helpful for further development of more accurate models for predicting ESP gas-liquid flow behaviors.

“…Further improvement of coupling design requires knowledge of the local fluid distribution at given operational points. There are many groups engaged in the analysis of fluid distributions of centrifugal pumps, axial pumps as well as hydro dynamic fluid couplings [1][2][3][4][5][6]. Here, numerical studies on various blade or inlet and outlet geometries were performed as well as optical measurement techniques which provide only local information in most cases.…”

“…Computer simulation experiments [9] are commonly used in addition. José A. Caridad [10] simulated the characteristics of centrifugal pump blades in the gas-liquid two-phase flow by CFD, and discovered its characterization. According to the velocity triangles of the centrifugal pump, Pei Ji [ 11] deduced the volume of the unsteady flow intensity, and the turbulent flow field of the unsteady flow in the low specific speed centrifugal pump was simulated.…”

The hydraulic characteristics of a centrifugal pump change when in a plateau, while the corresponding law is unclear. Therefore, experimental research needs to be undertaken on the hydraulic characteristics of a centrifugal pump in a plateau for a quantitative analysis of the changing law. In this paper, the working status of a centrifugal pump in a plateau was simulated by the method of controlling the inlet vacuum so as to acquire the pressure and the flow data under different working conditions. The corresponding conclusions were reached by using thorough data analysis, which shows that with every 500m increase in altitude, the accompanying pump pressure decreased by about 5%-10%, the flow decreased by about 2%-5% and the overall efficiency decreased by about 2%-9%. This theoretical analysis shows that the increase in pump frictional loss is the fundamental reason for the change in the hydraulic characteristics of a centrifugal pump in a plateau.
