Vertical slug flow is characterized by the rise of long bullet-shaped gas bubbles with a
diameter almost matching that of the tube-Taylor bubbles. Liquid slugs separate consecutive …

We provide the high speed flow visualization results for the closed loop pulsating heat pipes
(PHPs). It is identified that there exists the bulk circulation flow which lasts longer and the …

Slug flow is a dynamically complex two-phase flow pattern. A wide variety of industrial gas-
liquid systems operate under slug flow conditions for not only flow transportation purposes …

The occurrence of the slug flow pattern is frequently detected in the petroleum industry.
Theoretical and experimental works on the complex behaviour of this flow pattern are …

Although develo** gravity-driven slug flow frequently occurs in oil and gas, and energy
systems, its development dynamics remain underexplored; this gap, in turn, has left the …

Slug flow is one among the different flow patterns that two-phase flows can assume. This
pattern is composed of a Taylor bubble and a liquid slug and can commonly occur in pipes …

Experimental investigation on vertical upward co-current air–water slug flow was carried out
at atmospheric pressure, employing optical probes and high-speed photography …

In this study, a velocity field model around a Taylor bubble is established after the analysis of
the disturbed region around the bubble. The model combines the continuity and yield stress …

A large number of studies have been conducted to understand the slug flow characteristics
of air-liquid two-phase flow in horizontal pipes and to capture parametric trends of critical …

The flow field in the liquid phase of high viscous oil and air two-phase slug flow were
experimentally studied under laminar flow conditions. The horizontal 50.8-mm (2-in.) inner …
