The slug frequency (SF), which refers to the number of liquid slugs passing through a pipe
during a specific time, is an important parameter for characterizing the multiphase …

Flow visualisation experiments are carried out to analyse the internal structure of different
sub-regimes of slug flow. Five distinct slug flow sub-regimes are identified based on the …

This paper investigates the unsteady hydrodynamic behaviour of slug flow occurring within
an air–silicone oil mixture, within a horizontal 67 mm internal diameter pipe. A series of slug …

The objective of this paper is to investigate the motion of a single Taylor bubble through
stagnant Newtonian liquid in an inclined pipe by performing a complete dimensionless …

Flow visualisation experiments are reported for intermittent regime of gas–liquid two-phase
flow. Intermittent flow characteristics, which include plug/slug frequency, liquid plug/slug …

Pseudo-slug flow occurs between the slug and segregated flows and occupies a non-
negligible area in the flow pattern map especially for gas condensate pipeline/wellbore …

This paper presents an investigation of the hydrodynamics of slug flow in a vertical 67 mm
internal diameter riser. The slug flow regime was generated using a multiphase air–silicone …

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 …

Slug frequency is an important input parameter in most mechanistic and semi-mechanistic
models used for estimating slug flow characteristics such as pressure gradient, slug length …

The number of slug units that traverses a particular point at a given time within a defined
pipe cross-section is known as slug frequency. The behaviour of this critical parameter for …
