The effect of drag‐reducing agents (DRAs) on fluid flows in straight pipes has been well
documented. Key among these is the effect of DRAs on turbulence statistics (Reynolds …

This paper presents a comprehensive review of investigations on liquid-liquid flow through
horizontal pipes. Characteristics like flow pattern, pattern transition including phase …

The flow pattern in two-phase flows is a significant factor which influences many other
parameters such as heat transfer and pressure drop in pipelines. In the present work, flow …

The effect of adding a drag reducing polymer in the water phase during horizontal oil–water
flows was studied experimentally. Experiments were carried out in a 14 mm ID acrylic pipe …

As the water content in heavy oil gathering systems increases to 70–90% and large-scale
popularization of cold transportation. Understanding the characteristics of heavy oil-water …

High-pour point and high-viscosity crude oil can be gathered and transported below the
pour point during a high water-cut period. However, oil under these conditions can easily …

Flow patterns are important for pressure gradient calculation and corrosion protection. In this
study, the characteristics of oil–water flow were investigated in a horizontal acrylic pipe with …

Wax deposition in oil-water stratified flow is commonly encountered onshore and offshore oil
production pipe systems, and typically reduces transportation capacity of oil. The accurate …

Flow patterns encountered during the flow of a waxy crude oil and water in a horizontal
pipeline were experimentally studied at a temperature 4° C greater than the wax …

Pressure drops were measured during the co-current flow of a highly viscous oil and water
in a horizontal stainless steel pipe with 40 m in total length and 25 mm inner diameter …
