Two-phase annular flow in vertical pipes is one of the most common and important flow
regimes in fluid mechanics, particularly in the field of building drainage systems where …

Jets and plumes have been the focus of quantitative investigations since the mid‐1950s.
These investigations intensified following the Deepwater Horizon oil spill, in which …

Disturbance waves are of central importance in annular flows. Such waves are
characterised by their large amplitudes relative to the mean film thickness, their high …

Basaltic pyroclastic volcanism takes place over a range of scales and styles, from weak
discrete Strombolian explosions (∼ 102–103kgs− 1) to Plinian eruptions of moderate …

In order to solve the gravity transportation problems of backfilling slurry by pipelines in
Hemushan Iron Mine, solid-liquid two-phase flow theory and computational fluid dynamics …

The two-phase pressure drop in vertical industrial pipes is mainly determined by gravitation
and acceleration of the fluid, which means that the void fraction is key an important …

Oil/gas pipe flows are expected to exhibit significantly different behavior at high oil
viscosities. Effects of high-viscosity oil on flow pattern, pressure gradient, and liquid holdup …

An experimental investigation was carried out on viscous oil–gas flow characteristics in a 69
mm internal diameter pipe. Two-phase flow patterns were determined from holdup time …

In the churn flow regime, periodical interfacial structures such as liquid slugs and huge
waves can coexist and undoubtedly, a phase property such as liquid viscosity can dominate …

The effect of high oil viscosity on upward two-phase gas-oil flow behavior in vertical pipes
was experimentally and theoretically studied. A total of 149 air-high viscosity oil and 21 air …
