TLDR
Lau et al. as mentioned in this paper used algebraic closure relations to simulate large-scale gas/liquid contact apparatusses, such as bubble columns, which is essential for the optimization and further development of many bio-chemical and metallurgical processes.About:

Dynamics of an initially spherical bubble rising in quiescent liquid
TL;DR: It is reported that the dynamics is fully three-dimensional, and provide a broad canvas of behaviour patterns, and a perfect correlation between large shape asymmetry and path instability is established.
Journal ArticleDOI
Review of direct numerical simulation of fluid–particle mass, momentum and heat transfer in dense gas–solid flows
TL;DR: In this article, a review of the use of direct numerical simulation (DNS) models for the study of mass, momentum and heat transfer phenomena prevailing in dense gas-solid flows is presented.
Journal ArticleDOI
Agitation, Mixing, and Transfers Induced by Bubbles
TL;DR: In this paper, a k−3 spectral subrange and exponential probability density function for bubble-induced agitation (BIA) was derived from a simulation of bubbles randomly distributed within a liquid.
Journal ArticleDOI
Two-phase bubbly flow simulation using CFD method: A review of models for interfacial forces
TL;DR: In this article, the current status of interfacial forces models within the prospect of two-phase bubbly flow CFD simulation are summarized and then parametric dependence, and ranges of applicability of these models are reviewed.
Journal ArticleDOI
Dynamics and mass transfer of rising bubbles in a homogenous swarm at large gas volume fraction
TL;DR: In this article, the collective effect on both bubble dynamics and mass transfer in a dense homogeneous bubble swarm for gas volume fractions alpha up to 30 % was investigated, where a dual-tip optical probe was used to determine the interfacial area between the gas and the liquid, and the transfer of oxygen from the bubbles to the water was measured from the time evolution of the concentration of oxygen dissolved in water.

Bubbles, Drops, and Particles
TL;DR: In this paper, the authors evaluated the applicability of the standard κ-ϵ equations and other turbulence models with respect to their applicability in swirling, recirculating flows.

A front-tracking method for viscous, incompressible, multi-fluid flows
TL;DR: In this paper, a method to simulate unsteady multi-fluid flows in which a sharp interface or a front separates incompressible fluids of different density and viscosity is described.

Sedimentation and fluidisation: Part I
J.F. Richardson,W.N. Zaki +1 more
TL;DR: In this paper, the effect of concentration of suspended particles upon their rate of settlement was examined experimentally, and the experimental results obtained in the present work were compared with those predicted from this theory.
Journal ArticleDOI
Transverse migration of single bubbles in simple shear flows
TL;DR: In this article, trajectories of single air bubbles in simple shear flows of glycerol-water solution were measured to evaluate transverse lift force acting on single bubbles, and the authors concluded that the critical bubble diameter causing the radial void profile transition from wall peaking to core peaking in an air-water bubbly flow evaluated by the proposed CT correlation coincided with available experimental data.

The Motion of High-Reynolds-Number Bubbles in Inhomogeneous Flows
Jacques Magnaudet,Ian Eames +1 more
TL;DR: In this article, a trident approach consisting of experimental, analytical, and numerical work has given a clearer description of the hydrodynamic forces experienced by isolated bubbles moving either in inviscid flows or in slightly viscous laminar flows, and a significant part of the paper is devoted to a discussion of drag, added mass force, and shear-induced lift experienced by spheroidal bubbles moving in inertially dominated, time-dependent, rotational, nonuniform flows.
