TL;DR: In this article, a three-dimensional non-linear fluid-solid coupling finite element model was established based on the finite element software ABAQUS for hydraulic fracturing treatment, in which perforation, wellbore, cement casing, one pay zone, two barriers, micro-annulus fracture and transverse fracture were included.

TL;DR: In this article, the authors investigated the gas-liquid two-phase flow patterns at the entry section and the impellers inside a three-stage rotodynamic multiphase pump designed by the authors.

TL;DR: In this paper, a rotodynamic multiphase pump (MPP) was designed and installed in front of the pump, and the structure of the buffer tank and the scheme of openings on the central porous pipe were designed and presented.

TL;DR: In this article, a three-stage helico-axial multiphase pump with new designed impellers and high rotational speed was evaluated in both single and two-phase experiments.

TL;DR: In this article, a novel optimization design method for the multiphase pump impeller is proposed through combining the quasi-3D hydraulic design (Q3DHD), the boundary vortex flux (BVF) diagnosis, and the GA.
