This work demonstrates the artificial neural network (ANN) ability for predicting slug liquid
holdup (H LS), using 2525 measured points from 20 experimental studies. Six variables …

Flow pattern is an important engineering design factor in two-phase flow in the chemical,
nuclear, and energy industries, given its effects on pressure drop, holdup, and heat and …

Pseudo-slug (PS) and churn (CH) flows are among the least understood flow patterns for
gas-liquid flow in pipes, despite their importance in many engineering applications. Owing to …

The worst-case discharge during a blowout is a major concern for the oil and gas industry.
Various two-phase flow patterns are established in the wellbore during a blowout incident …

Pseudo-slug flow is a subset of intermittent flow. It is commonly encountered in oil and gas
production operations of deviated natural gas wells or pipelines with liquid accumulation …

This study attempts to address the unavailability of mechanistic model for pseudo-slug flow
and the limitation of upscaling studies of multiphase flow at elevated pressures. Pseudo-slug …

Two-phase flow models play a fundamental role in the design, improvement, and operation
of oil and gas production systems. Considering very large high-viscosity oil reserves around …

The friction coefficient is an important factor that affects the accurate calculation of wellbore
annular pressure distribution and is of great significance for the safety of drilling operations …

Understanding two-phase flow behavior in upward vertical wells is critical for proper well
design and operation. Current two-phase slug flow models and their closure relationships …

Gas void fraction plays a significant role in determination of several multiphase flow
parameters. Good insight of its behaviour coupled with accurate prediction is imperative for …
