“…Of these, with respect to the theoretical research on multi-phase pump pressurization, Miao et al 15,16 proposed a new design method for a multiphase pump pressurization unit on the basis of an original pump design theory, and a basic energy equation and Bernoulli equation for the axial flow pump were put forward toward a theoretical analysis method on the basis of the helical axial multi-phase pump's headflow characteristic curve. Yu et al 17,18 proposed a hydraulic design method for the impeller within the multi-phase pump based on the iteration of positive and negative problems. Li and Zhang et al 19,20 also studied the hydraulic design and the impeller optimization of the axial flow multi-phase pump, respectively.…”

In order to improve the working performance of the impeller in a multi-phase pump under different working conditions and expand the range of the high-efficiency areas of the multi-phase pump, each section of the impeller was divided into an inlet section, middle section and outlet section. The pressurization performance of different areas within the impeller was obtained by numerical calculation under different flow rates and different gas volume fractions, respectively. The results show that the pressurization performance of the different areas within the impeller can be predicted well. In the first half of the impeller, when the blades were closer to the rim, the pressurization performance was stronger, and in the second half of the impeller, when the blades were closer to the hub, the pressurization performance was stronger. With an increase in the flow rate, from the inlet section to the outlet section, the pressurization performance of each stage of the impeller gradually decreased, and the strongest pressurization performance area was always in the inlet section with no obvious movement. With the increase in the gas volume fractions, the pressurization value of each stage of the impeller dropped faster, except for the outlet section. When there was an increase in the flow rate or the gas volume fraction, the inlet section was influenced the most and the outlet section was influenced the least. The research results provide an important theoretical basis for further optimization of the impeller design for a multi-phase pump.

“…Furthermore, they discussed the influence of the operating parameters on the pump's performance and then optimized these parameters and the geometrical structure of the impeller. Yu and colleagues [15][16][17] conducted a hydraulic design of a rotodynamic type MPP using a combined approach of inverse design and computational fluid dynamics (CFD) analysis; in addition, the numerical simulation of gas-liquid mixture flow was also used for internal flow analysis. Zhu and colleagues 18,19 compared three different prototype pumps; they also analyzed the influence of different geometric parameters of compression cells on the hydraulic performance of the MPP.…”

To investigate the gas-liquid two-phase flow in a three-stage multiphase pump, numerical simulations and visualization experiments were performed. A mixture of air and water was selected as the medium. A three-dimensional flow field of the three-stage multiphase pump designed by authors was simulated employing the commercial computational fluid dynamics software ANSYS-CFX to solve the Navier-Stokes equations for steady flow and unsteady flow. The differential pressure of each stage and change characteristic of gas volume fraction under various inlet gas volume fraction were compared via steady simulations. The distribution characteristics of pressure and gas volume fraction in three stages were studied, and the movement of gas pockets in impellers was discovered via unsteady simulations as well. Four types of flow patterns were observed during the visualization experiments with the increasing inlet gas volume fraction. The results of the experiment reveal that the positions and characteristics of the gas pocket were similar to the results from the unsteady simulations, which verify the reliability of the simulations.
