Methods for flow visualization have been decisive for the historical development of fluid
mechanics. In recent years, technological advances in cameras, lasers, and other devices …

The working capability of multi-stage pumps, such as electrical submersible pumps (ESPs)
handling multiphase flow, has always been a big challenge for petroleum industries. The …

The operation of centrifugal pumps with gas-liquid mixtures is a common problem in the oil
and gas industry. The main problem is related to the accumulation of gas inside the Electric …

Determining the characteristics of gas-liquid two-phase flow in centrifugal pumps is essential
for a better understanding of pump performance. In this study, a visualization investigation …

Centrifugal pumps are present in the daily life of human beings. They are essential to
several industrial processes that transport single-and multi-phase flows with the presence of …

The flow pattern in centrifugal pump is critical for better understanding the effect of inlet gas
on the pump performance. In this study, the bubble dynamic behavior and its influence on …

In this study, a numerical simulation method based on Eulerian–Eulerian model and
population balance model (PBM)(ie, computational fluid dynamics (CFD)–PBM coupling …

Pump inducers are usually employed within a limited flow rate range since the performance
is known to drop out significantly far from their design point. Therefore, finding an optimal …

The objective of the current work is to present the development of a Particle Tracking
Velocimetry (PTV) algorithm for the analysis of oil drops behaviour in two-phase oil–water …

Two-phase flows generally represent an adverse condition for centrifugal pumps. Research
about this topic tends to be focused on performance evaluation through experimental …
