Numerical Investigation of Vertical Plunging Jet Using a Hybrid Multifluid–VOF Multiphase CFD Solver [PDF]
International Journal of Chemical Engineering, 2015 A novel hybrid multiphase flow solver has been used to conduct simulations of a vertical plunging liquid jet. This solver combines a multifluid methodology with selective interface sharpening to enable simulation of both the initial jet impingement and ...

Experimental study of turbulent bubbly jet. Part 1. Simultaneous measurement of three-dimensional velocity fields of bubbles and water [PDF]
, 2022 This study proposes a method for simultaneous measurements of time-resolved three-dimensional velocity fields of the dispersed and continuous phases of a turbulent bubbly jet at a low void fraction using Lagrangian particle tracking (LPT) velocimetry ...

The Fluidization Backwash Method of Filter Beds by Air-water Bubbly Flow
Journal of Water and Environment Technology, 2020 A novel fluidization backwash method by the air-water bubbly flow with air bubbles of various sizes has been proposed for rapid filters. The backwash efficiency is closely related to the bubble wake motion.

Jets from collapsing bubbles [PDF]
Proceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 1999 When an asymmetric bubble collapses it generally produces a well defined high velocity jet. This is remarkable because one might expect such a collapse to produce a complex or chaotic flow rather than an ordered one. I present a dimensional argument for the ubiquity of jets from collapsing bubbles, and model the aspherical collapse of a bubble with ...

Multiphase digital particle image velocimetry in a dispersed, bubbly, axisymmetric jet [PDF]
, 2002 A particle image velocimetry (PIV) technique developed for application to two-phase flows is presented and validated. The technique is capable of simultaneously measuring carrier and bubble phase velocities on a plane.

Transition from bubbling to jetting in a coaxial air–water jet [PDF]
Physics of Fluids, 2004 In this Brief Communication we study experimentally the flow regimes that appear in coaxial air–water jets discharging into a stagnant air atmosphere and we propose a simple explanation for their occurrence based on linear, local, spatiotemporal stability theory.

CFD Approaches for Modelling Bubble Entrainment by an Impinging Jet
Science and Technology of Nuclear Installations, 2009 This contribution presents different approaches for the modeling of gas entrainment under water by a plunging jet. Since the generation of bubbles happens on a scale which is smaller than the bubbles, this process cannot be resolved in meso-scale ...

Interaction between two spherical bubbles rising in a viscous liquid [PDF]
, 2011 The three-dimensional flow around two spherical bubbles moving in a viscous fluid is studied numerically by solving the full Navier-Stokes equations. The study considers the interaction between two bubbles for moderate Reynolds numbers (50 ≤ Re ≤ 500, Re

Non -Intrusive Characterization of a Dispersed, Bubbly, Axisymmetric Jet. [PDF]
, 2000 This study investigated the effects of bubble size and phase distribution on the liquid and bubble flow fields in a dispersed, bubbly axisymmetric jet. Of primary interest was the interaction of the bubbles with large-scale structures in the developing ...
