Investigations of the Formation Mechanism and Pressure Pulsation Characteristics of Pipeline Gas-Liquid Slug Flows

Gaoan Zheng,
Pu Xu,
Lin Li
et al.

Abstract: The pipeline system is widely used in marine engineering, and the formation mechanism and flow patterns of two-phase slug flows are of great significance for the optimal design of and vibration prevention in a complex pipeline system. Aiming at the above problems, this paper proposes a modeling and solving method for gas-liquid slug flows. First, a VOF-PLIC-based coupling gas-liquid slug flow transport model is conducted. Second, to reduce the fuzzy boundary between the gas-liquid coupling interfaces, an artif… Show more

“…In recent years, computational fluid dynamics (CFD) technology has significantly advanced our understanding of fluid flow phenomena. Research by Qing Yan and Gaoan Zheng [15] has contributed to this field, particularly in investigating two-phase slug flow in pipelines. Yan focused on mixed-transport pipelines, using a VOF-based model to analyze slug flow formation.…”

“…G. Zheng et al [18] presented the multiphase modeling and solution method, which combines the RNG turbulence model and establishes a gas-liquid slurry flow model to simulate the transient flow properties, which calculates the volume fraction, gas flow rates, and pressure pulsation at different working conditions. Simulations were carried out to analyze the phase interface structure of long bubbles to explore the flow characteristics and flow pattern in complex multi-inlet pipelines.…”
