Transcriptome Analysis of the Central Nervous System of Sea Slug (Onchidium reevesii) Exposed to Low-Frequency Noise

open access: yesFrontiers in Marine Science, 2021
Low-frequency noise has become a marine pollutant that cannot be ignored, but most studies have focused on the behavioral and physiological effects on marine vertebrates, with few studies in marine mollusks.

Holdup and frequency characteristics of slug flow in concentric and fully eccentric annuli pipes

open access: yesJournal of Petroleum Science and Engineering, 2019
Slug liquid holdup and frequency for gas-liquid flows in horizontal and upward low-inclination annuli are investigated. The annulus consists of an outer pipe of 99 mm inside diameter and an inner pipe of 50 mm outside diameter. Two annulus configurations

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

open access: yesJournal of Marine Science and Engineering
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

An experimental investigation of the stochastic nature of slug flow [PDF]

open access: yesE3S Web of Conferences, 2023
Slug flow is widely encountered in oil and gas systems. It has an unsteady hydrodynamic behavior that motivated the development of mechanistic models to better understand and quantify the parameters of the flow. The present work investigated several slug

Experimental and Numerical Study on the Slug Characteristics and Flow-Induced Vibration of a Subsea Rigid M-Shaped Jumper

open access: yesApplied Sciences, 2023
The subsea jumper has become an essential part of subsea production systems as a gas–liquid mixing pipeline connecting the pipeline end manifold (PLEM) to the Christmas tree.

Numerical and experimental simulation of gas-liquid two-phase flow in 90-degree elbow

open access: yesAlexandria Engineering Journal, 2022
In the present research, the effects of four 90-degree horizontal elbows with different curvature radii (17, 34, 51, and 68 cm) and an identical rectangular cross-section (20 * 34 mm) on a gas–liquid slug flow pattern have been studied experimentally and

Onset of intermittent flow: Visualization of flow structures

open access: yesOil & Gas Science and Technology, 2021
The transition from stratified to intermittent air-water two-phase flow was investigated experimentally, by flow visualization and pressure drop signals analyses, in a 30 mm ID pipe.

Real-Time Detection of Slug Velocity in Microchannels

open access: yesMicromachines, 2020
Microfluidics processes play a central role in the design of portable devices for biological and chemical samples analysis. The bottleneck in this technological evolution is the lack of low cost detection systems and control strategies easily adaptable ...
