In the process of liquid-dominated offshore oil and gas transportation, long hydrodynamic
slugs are likely to occur in subsea pipelines at high liquid holdup. A large number of long …

A numerical study based on a one-dimensional two-fluid model is carried out to describe the
transient hydrodynamic slugging and terrain-induced severe slugging in a pipeline–riser …

A novel numerical scheme for slug capturing in pipes using a 1‐dimensional transient
hyperbolic 5‐equation 2‐fluid model is presented. Previous work has shown that 1 …

In this study, an extended two-fluid model (TFM) describing the gas-liquid two-phase flow
when gas influx occurs and an acoustic model describing sound propagation within section …

Improvement of the separation efficiency of the phases at the slug catcher has been always
questionable. In this study, gas–liquid two-phase flow is simulated numerically in vessel …

Managed pressure drilling (MPD) is a drilling technique used to address the narrow density
window under complex geological environments. It has widespread applications in the …

In this paper, two path-conservative schemes, namely Osher and PRICE-C schemes have
been used to solve isothermal compressible two-phase flows using four-equation model …

Previous work showed that a one-dimensional, hyperbolic, transient five-equation two-fluid
model can predict automatically the formation, growth, and subsequent development of …

This study presents a methodology using the correlation of numerical diffusion with the
standard two-fluid model to simulate the separated two-phase flow (gas–liquid) in a pipe …

In this paper, a numerical study is performed in order to investigate the effect of the virtual
viscosity on simulation of separated two-phase flow of gas-liquid. The governing equations …
