The simultaneous flow of gas, oil, and water forms various flow patterns due to the complex
interfacial relationships. Three-phase flow patterns are classified as the gas-liquid and liquid …

Reliable and accurate prediction of the transition from spherical cap bubble to slug flow is
crucial not only to the operation of industrial facilities such as the crude oil pipelines, bubble …

Blind-tee pipes are often employed in process piping systems used in offshore and subsea
oil and gas industry. The objective of the present study is to investigate the effects of blind …

Sub-regimes of intermittent two-phase flows through a sudden expansion have been
investigated experimentally. Two pipes of 30 and 40 mm ID connected by a sudden …

Flow pattern identification for simultaneous gas-liquid flow in pipes is a central problem in
the petroleum industry. However, there are many conventional methods used for flow …

A pipeline-riser system is a typical complex pipe configuration in which the non-uniformity of
gas/liquid flow is observed to be significant under certain flow rates. This article interprets …

Experimental investigations were conducted to study the evolution of air/water slug flow
characteristics through a horizontal sudden expansion having a ratio of A σ A= 0.444. A …

Assuring the displacement of trapped liquids from low sections by gas flow is essential for a
proper operation of high-pressure natural gas pipelines. Numerical investigation of the …

The simultaneous flow of gas, oil & water is frequently encountered in pipelines during
upstream petroleum operations. The multiphase flow results in different types of flow …

Curved pipes are essential components of subsea process equipment and some part of
production pipeline and riser. So far, most of the studies on of wax deposition and the …
