The aim of this study is to develop a model for the determination of the superficial velocities in horizontal and slightly inclined oil–water pipe flow conditions by using pressure gradient and mixture density information. In this article an invers

The gas-lift technique comprises the injection of gas bubbles in vertical oil wells to increase production. It is based on a reduction of the tubing gravitational pressure gradient. Several fluid-flow phenomena influencing such vertical gas-liquid fl

A simplified Euler–Euler model was developed for predicting the void fraction and velocity profiles in a vertical upward bubbly pipe flow. The main objective of this approach is to provide a tool for computing the gravitational pressure gradient as

We investigated the effect of bubble size on the drift–flux parameters at low liquid flow conditions by measuring the radial profiles of void fraction and phase velocities in a vertical bubbly pipe flow of diameter and height . To study the effect

The possibility to measure the velocity and size of individual bubbles in a high-void fraction bubbly flow is investigated by using a four-point optical fiber probe. The air bubbles have an initial spherical equivalent diameter ranging from 4 to 10 m

An upward air–water bubbly flow in a pipe was studied experimentally, special attention being paid to the transition from bubbly flow to slug flow. The pipe diameter was 72 mm and the height 18 m. The Reynolds number based on liquid flow was low-to
