Analysis of Fluid-Structure Coupling Vibration Characteristics of Pipeline Transporting Bubbly Fluid Medium: With Application to Luxury Passenger Ship Life Area Pipeline

Shock and Vibration, 2023
When pipelines are transporting bubbly fluid medium, due to the coalescence and breakage behaviours of the bubbles, the pressure distribution at the wall is not uniform and the structure response is more complex.

Reaction Systems for Bubbly Flows [PDF]

European Journal of Inorganic Chemistry, 2018
Reactive bubbly flows are at the heart of multiphase flows which are a major topic in chemical engineering since many bulk chemicals are produced in bubbly flows. However, the factors determining product yield and selectivity are often subject of complicated mass transfer effects.

Vortex Simulation of the Bubbly Flow around a Hydrofoil

International Journal of Rotating Machinery, 2007
This study is concerned with the two-dimensional simulation for an air-water bubbly flow around a hydrofoil. The vortex method, proposed by the authors for gas-liquid two-phase free turbulent flow in a prior paper, is applied for the simulation.

Transition Criterion of Bubbly-slug Flow Pattern in Rectangular Narrow Channel

Yuanzineng kexue jishu, 2022
In the two-phase flow system, the flow pattern affects the frictional resistance and heat transfer characteristics of the system. Accurate identification of different flow patterns is of great significance to the calculation of twophase flow.

Experimental and theoretical study of the gas–water two phase flow through a conductance multiphase Venturi meter in vertical annular (wet gas) flow [PDF]

, 2011
Annular gas–liquid two phase flow widely occurs in nuclear industry. Various combinations of techniques have been employed in annular gas–liquid two phase flows to measure the flow parameters (e.g. liquid film thickness, gas volume fraction and the phase

Bubbles and bubbly flows

International Journal of Multiphase Flow
Bubbles and bubbly flows are omnipresent in nature and technology, showing a multitude of phenomena, which can be either beneficial or a hindrance. In any case, for their control and their applications, it is crucial to understand their fundamentals and therefore from the very beginning of the International Journal of Multiphase Flow they have been ...

Flow Regimes and Transitions for Two-Phase Flow of R152a During Condensation in a Circular Minichannel

Frontiers in Energy Research, 2021
Two-phase flow regimes were experimentally investigated during the entire condensation process of refrigerant R152a in a circular glass minichannel. The inner and outer diameters of the test minichannel were 0.75 and 1.50 mm.
